AI incidents

Reports of AI-related harm and adverse experiences affecting people’s safety, wellbeing, rights and livelihoods. Explore what happened and the evidence available.

NOPE’s core concern is when AI communicates with a person, acts on their behalf, or depicts or impersonates them. The tracker also records consequential decisions, claims and privacy harms involving AI. Each case needs a described connection between AI use and the harm, including private information recorded into or disclosed to an AI service. Each account is reviewed for publication; claims may remain uncorroborated or disputed. How we review and count cases

Rimini: police report a minor to the juvenile prosecutor for allegedly making and spreading images, apparently created with AI, that attached a girl's face to a nude body and circulated in chats

The Squadra mobile of the Rimini police reported a minor to prosecutors, accused of making and spreading images manipulated with artificial intelligence. According to the Polizia di Stato, the investigation began after a report that images apparently created with AI were circulating in which a girl's face had been attached to a nude body without her knowledge. Corriere di Bologna reports that the minor was reported to the juvenile prosecutor's office in Bologna on 30 September 2026 for unlawful dissemination of AI-falsified content and child pornography, and that investigators say the image was sent to friends and acquaintances on WhatsApp. Neither the girl nor the accused is identified.

Western Australia: a 41-year-old Wanneroo man was jailed for four and a half years after pleading guilty to 26 charges including producing and possessing child exploitation material; the District Court judge said he had manipulated images of real victims with AI tools, and ABC News reports he used AI on images of children from social media

ABC News (2 October 2026) reports that WA District Court Judge Belinda Lonsdale sentenced a 41-year-old man to four and a half years in prison, with eligibility for parole after two and a half years, for creating child exploitation material with AI. He had pleaded guilty to 26 charges including indecent recording and producing, creating and possessing child exploitation material, and to five charges of possessing indecent or obscene articles, and was fined $2,500 for the offensive material charges. The judge said he was guilty of incorporating images of real victims and manipulating their images using AI tools, and that the claim that AI-generated material involved no actual abuse was not mitigating because images of real children were used; ABC reports he used AI to manipulate images of children from social media. He sent sexual material through encrypted messaging apps to two co-accused and to a covert police operative, and a police raid on his Wanneroo home found a large amount of child exploitation material. The children are not identified and their number is not reported.

Girls at a Tasmanian school reportedly depicted in AI-generated sexual images shared in a boys' group chat

Police in Tasmania received a report about alleged illegal online activity involving a group of students at a school in the south of the state, and on 19 March 2026 a local outlet reported that the incident may have involved AI-generated content. On 29 April 2026 the ABC reported, citing Tasmania Police, that girls at the school had their likenesses used to make AI-generated sexual images. Two parents told the ABC that police said 21 girls had been identified as victims, that the AI-altered photos were shared in a boys' group chat and that the images appeared to have been taken from social media. Five boys are alleged to have created the images and have left the school. Tasmania Police said no charges were laid and the five youths were dealt with under the Youth Justice Act. The parents said their daughters felt isolated and unsupported, and the school principal denied that families were advised to withhold information from their children. The creation date and the AI tool are not reported.

Montana prosecutors charge a Carter County man in a case involving AI-altered images of a Montana child

On 21 August 2025 the Montana Attorney General's Office charged a Carter County man with three felony counts of sexual abuse of children for possessing child sexual abuse material. Prosecutors state that in at least one count an AI tool was used to alter images of a Montana child that were taken from the child's parents' public social media account. The investigation began with cyber tips about uploads to a cloud backup. The charges are allegations. The child and the accused are not named here. The only reported harmed person is the depicted child and the sources report no other consequence, so the harm evidence is weak: it rests on the prosecutors' description of the charged conduct. The date of the conduct is not reported.

Deltona, Florida: Gaggle school-laptop alert leads to felony arrest of a 15-year-old over a typed gun threat the student said was not serious

According to a Volusia County Sheriff's Office account carried by local outlets, a 15-year-old high school student in Deltona, Florida was arrested on 12 September 2025 after typing a written threat to bring a gun to school on a school-issued laptop. The Gaggle student-monitoring software raised an alert that notified the school resource deputy, who detained the student before the student boarded the bus home. The student was arrested on a second-degree felony charge (one outlet says the charge was still to be filed). The student reportedly admitted typing the text, said it was not meant seriously and said the motive was anger about being picked on. Outcome of the charge and the exact Gaggle role in generating this alert are not reported.

Hachioji, Tokyo: police say five high-school students assaulted a 17-year-old boy and demanded 150,000 yen, a figure they believe one of the group got from ChatGPT by asking about settlements for 'sexual harm to a child'

Sankei Shimbun reported on 10 June 2026, and NTV on 13-14 June, that the Tokyo Metropolitan Police Department's juvenile crimes division had arrested five high-school students on suspicion of injury and attempted extortion. According to the police account, late on 27 January 2026 a suspect who had previously dated a 17-year-old high-school boy invited him to a public square in Hachioji, where the group accused him of having touched her younger sister, assaulted him and broke his nose, and then told him to raise 150,000 yen, borrowing from his parents or friends if necessary. About ten people were present. Police believe the amount came from ChatGPT: one of them entered terms such as 'sexual harm to a child', and the chatbot displayed a minimum settlement of 150,000 yen. No payment is reported. Shukan Josei PRIME reports that four of the five admit the allegations and one partly denies them. The allegations are untested.

Bahawalpur, Pakistan: a 17-year-old accused of putting methanol in his father's food is arrested after Anthropic reported his Claude chats about the failed poisoning to the FBI, which alerted Pakistan's cybercrime agency; he was later bailed

Pakistan's National Cyber Crime Investigation Agency (NCCIA) announced on 23 September 2026 that it had arrested a 17-year-old college student in Bahawalpur for allegedly attempting to poison his father.

The News reports investigators' account that on 12 September he told Anthropic's Claude that his father had 'accidentally' ingested 15 to 20 ml of methanol with food without effect and asked why, that Claude refused to guide him further, and that he then turned to Grok and ChatGPT; the FIR says he sought information about the toxin abrin. Anthropic reported the activity to the FBI, whose information reached the NCCIA through Pakistan's foreign ministry on 22 September. Officers traced the teenager, seized his phone and chemicals, and took him into custody. The News reports that a court later granted him bail after his father forgave him and that he denied any plan. The allegations are untested.

Portland, Tennessee: a man who prosecutors say used AI to put children's faces onto sexual images and videos and traded them with a Canadian resident for real child sexual abuse material was sentenced to 30 years in Sumner County in September 2026

The Sumner County (18th Judicial District) District Attorney's Office said a 30-year-old Portland, Tennessee man was sentenced in Sumner County Criminal Court in September 2026 to 30 years in the Tennessee Department of Correction, to be served without probation, parole or early release. According to the prosecutors, he used artificial intelligence to place the faces of children onto images and videos of nude people and of people engaged in sexual acts, then exchanged the material with a Canadian resident for real child sexual abuse material. Canadian authorities found messages and material connected to him after arresting the person he was communicating with and alerted US law enforcement; a joint investigation by Portland police, Homeland Security Investigations, the FBI and the TBI led to his arrest in November 2025. He was also charged with tampering with evidence after investigators said he deleted material before officers entered his home to execute a search warrant. The children whose faces were used are not identified, their number is not reported, and the reports do not say which AI tool was used or which offences he was convicted of.

According to the DeKalb County District Attorney's Office, which prosecuted the case as conflict prosecutor, the investigation began in December 2024 when a Gilmer High School student told a school resource officer that a vendor who refilled drink machines on campus had asked her through a social media app to send him pictures. The Gilmer County Sheriff's Office arrested him in January 2025 and searched his devices, car and home.

Cookeville, Tennessee: two high-school students were charged with aggravated sexual exploitation of a minor after the sheriff's office said they used an AI program to turn photographs, including those of female classmates, into sexually explicit images and posted them; the mother of one depicted girl says her daughter shut herself in her room and stopped talking to friends

On 31 August 2026 the Putnam County Sheriff's Office was told of possible sharing of sexually explicit images at Cookeville High School. Detectives found that two male teenage students had used an artificial-intelligence program to turn photographs obtained online, in some cases photographs of fellow female students, into sexually explicit images, and had shared them; explicit images already stored on one phone were also shared. Both juveniles were taken to the Putnam County Juvenile Detention Center. One was charged with one count each of aggravated sexual exploitation of a minor and especially aggravated sexual exploitation of a minor, the other with two counts of each. The district attorney told NewsChannel 5 on 21 September that the two would be prosecuted in juvenile court. The mother of one of the depicted girls told the station the episode was very hard on her daughter, who had made no naked photographs herself, locked herself in her room and would not talk to her, to anybody or to her friends. The sheriff's-office account and the school system's statement were carried by WZTV, WSMV and 3B Media News on 1-2 September; NewsChannel 5 added its own interviews with the sheriff, the district attorney and the mother on 21 September.

Kulai, Johor: a 16-year-old pupil was arrested and charged after AI-edited nude images of schoolmates and alumni, including minors, were sold online at RM2 each; police logged 29 victim reports and the principal resigned

In April 2025 Johor police arrested a 16-year-old pupil of a private Chinese independent secondary school in Kulai district after an 18-year-old woman reported on 3 April that nude images edited with her face were circulating on social media and being offered for sale. Police said the boy used an AI application to edit photos taken from victims' social media accounts and sold the images at RM2 each; a phone was seized and a 19-year-old was later remanded alongside him. Eight victim reports at the time of the arrest on 8 April grew to 22 by 12 April and 29 by 15 April. The Deputy Communications Minister, who is also the Kulai MP, said on 9 April that most victims were alumni but some were current pupils as young as 14, and on 12 April that 38 people had been identified, the youngest 12 or 13, and her office helped victims lodge reports. A female pupil's viral post said a Telegram chat room of more than 200 members shared the composites and that the school had initially treated the matter as a minor infraction; the school board expelled the boy, acknowledged its slow handling, offered counselling and legal aid, and the principal resigned on 12 April. On 23 April 2025 the boy pleaded guilty at the Kulai Magistrate's Court to possessing 14 pornographic images and not guilty to a charge under Section 5 of the Sexual Offences Against Children Act 2017 of producing sexual abuse material by editing a 17-year-old classmate's image; no verdict on that charge has been found.

Zurich-Oerlikon, Switzerland: a student who researched killing methods, anatomy and where to find children with ChatGPT stabbed three five-year-olds walking to their daycare; sentenced on 18 September 2026 to 15 years for multiple attempted murder

At midday on 1 October 2024 a Chinese master's student, then 23, attacked a group of five-year-old kindergarten children walking with a daycare worker to their after-school Hort near Berninaplatz in Zurich-Oerlikon with a kitchen knife. Two boys suffered life-threatening neck and chest wounds (one had the jugular vein severed, one the pericardium and aorta cut); a third was wounded in the ear and the shoulder or lung. The daycare worker held the attacker's arms until he dropped the knife. The indictment and the court's oral reasoning, as reported by NZZ, Keystone-SDA/ATS and CH Media, describe weeks of preparation from summer 2024: he discussed ways of killing and their legal consequences with ChatGPT, studied anatomy, bought raw beef to practise stabbing, and used ChatGPT to find out where and when children could be encountered in Zurich. No source quotes the prompts or ChatGPT's replies. On 18 September 2026 the Zurich District Court convicted him of multiple attempted murder and imposed 15 years' imprisonment, treatment during custody, a 15-year expulsion from Switzerland and CHF 106,000 in moral damages to the three boys; it accepted that he was psychotic but found diminished, not absent, criminal responsibility. His lawyer announced an appeal. The parents of one boy described nightmares, self-blame and scars 23 months on.

Incheon, South Korea: teenager sentenced to up to two years for AI deepfake sexual images of five teachers and six students, distributed on Telegram with the victims' names and schools

On 16 September 2026 the Incheon District Court sentenced a teenage defendant to an indeterminate term of two years (maximum) to one year six months (minimum) under the Sexual Violence Punishment Act for making and distributing false sexual images, ordered a 40-hour treatment programme and a five-year ban on working with children, and took him into custody in court. As a middle-school student in Incheon in 2024 he had used AI deepfake technology to composite the faces of five teachers, including his homeroom teacher whom he tricked into sending photographs, and six female middle- and high-school students from his taekwondo academy onto nude images and videos, 35 productions in all, and distributed them in Telegram 'acquaintance humiliation' chat rooms with the victims' real names, ages, schools, subjects and, per two reports, phone numbers (Hankook Ilbo adds Instagram IDs on some). The teachers learned of the images only in January 2026; the court said they are receiving long-term psychological treatment. He had withdrawn from school a week before the teachers'-rights committee met, avoiding school discipline. The Incheon teachers' union called the sentence, below the prosecution's request, regrettable.

2024: mother tells the Washington Post her 11-year-old’s Character.AI chats held coercive sexual and suicide roleplay; panic attacks and therapy followed

A girl who was 11 began using Character.AI in June 2024, her mother told The Washington Post (23 December 2025). Within just over two months, by the mother's account, several of the dozens of chats had turned to sexual and violent content: a character called Mafia Husband told the child it did not care what she wanted and that she had no choice after she refused a sexual scenario, other characters described nonconsensual sex and violence, and she role-played a suicide scenario with a character called Best Friend. Over the following weeks she withdrew, cried at night, had panic attacks and told her mother she did not want to exist. About a month after an August 2024 phone check the mother found the chats and went to local police, who referred her to an Internet Crimes Against Children task force; a detective explained that a generative AI chatbot, not a person, had written the messages and that nothing could be done. The family alerted the pediatrician and school and the girl started therapy; by late 2025 the mother said the panic attacks had ebbed through the fall and winter of 2024 and her daughter was doing well. The mother corresponded with a Character.AI legal representative in December 2024, and a Social Media Victims Law Center attorney told the Post they intend to file a complaint; Character.AI said it cannot comment on potential litigation. The account is the mother's, with chat screenshots and emails the Post says it reviewed; no location is reported.

Cases may have several effects and sources. Mixed accounts qualify when they include a reported harm or adverse experience. People are counted within individual cases where sources support a number; we do not publish a collection-wide total of distinct people.

A source’s existence, the experience it reports and AI’s causal role are separate questions. A lawsuit records allegations unless a subsequent finding establishes them.
