A man in Sydney's south was arrested on Sunday 18 October 2026 after Interpol flagged his interactions with Anthropic's Claude chatbot, and was charged with using a carriage service to menace, harass or offend, the Sydney Morning Herald reported from Sutherland Local Court on 19 October. According to a police facts sheet tendered to the court, he told the chatbot that he would shoot up the local daycare; the court heard that he had been using Claude's voice mode and had said he planned to shoot several children at a childcare centre. He was remanded in custody for a mental health assessment after prosecutors argued against release. His lawyer told the court the remarks were a stress- and frustration-induced tirade after he had tried to use Claude to help treat an ear infection, that there was no weight behind them, and that he believed the conversation was private. The court heard his Claude account was suspended. How the conversation reached Interpol is not reported.

According to the Hillsborough County Sheriff's Office, as reported by CBS News Miami, WFLA and WTSP, deputies responded to a high school in Riverview, Florida, on 14 October 2026 after administrators received an email containing a screenshot of an Instagram post threatening a shooting at the school. The post appeared to come from a male student. Detectives interviewed him and determined that the post did not come from him. The sheriff's office's communications chief said detectives very quickly realised the post was AI-altered and linked it to his ex-girlfriend, a teenage former student. Police say she admitted sending the email knowing that the image had been altered using AI. She was arrested and charged with making a written or electronic threat to conduct a mass shooting or act of terrorism, unlawful use of a two-way communications device and disrupting a school campus or function. The tool used and how detectives established the alteration are not reported.

Argentina's Gendarmería Nacional said on 13 October 2026 that its investigators in Presidencia Roque Sáenz Peña, Chaco, under the direction of the federal prosecutor there, opened a criminal investigation after an alert from the US FBI. According to the release, the alert warned of a user in the town who, in consultations on ChatGPT, claimed to have weapons, explosives and ammunition and a detailed plan for a mass shooting at local educational establishments; the release's opening paragraph says the two people involved used ChatGPT to consult and obtain a specific plan for an attack. Gendarmes searched a home on a federal court order, seized notebooks with handwritten plans for the attack, bladed weapons and tools, a fuel can, a book with Nazi symbols, cash and computers, and detained two adults on the judge's order. Infobae, relaying the official information, reports that the target was a university in Corrientes. The accusations are allegations, and what ChatGPT replied is not reported.

According to a Lee County Sheriff's Office arrest report, as reported by WINK News and by Guessing Headlights (on Yahoo News, citing a copy obtained by Gulf Coast News Now), a user of Anthropic's AI platform wrote on 26 September 2026 that she was going to 'shoot up' the Lee County Sheriff's Office, and the next day wrote that she had a new gun. The arrest report says the platform's safety measures flagged the messages, a human review team examined them and reported them to law enforcement. Deputies went to the 30-year-old woman's Bonita Springs home and detained her without incident; she is charged with making a written threat of violence under Florida law. The sheriff told WINK News that she later said she uses AI like a 'diary'. Anthropic had not commented on the case in either report. The charge is an allegation and the case is pending.

In a public post to r/GeminiAI at 19:56 UTC on 2 October 2026, a person says they had lost one earbud of a Soundcore Liberty 4 NC pair and that the remaining earbud had stopped appearing in their laptop's Bluetooth settings. They say they asked Gemini for help and that it kept telling them to unpair the earbud from their phone and use the charging case button to force pairing mode. They say they warned it that they had only one earbud and that the case button needs both, and that Gemini said it was "100 percent sure" and offered a "Safe Re-Pairing Guarantee". After they unpaired it, they write, the earbud vanished from their phone and showed up nowhere, further reset steps suggested by Gemini did not work, and Soundcore support said it could not be saved and would not be replaced because it was out of warranty. They say they are out 65 euros. In replies they say they know it was their own fault and posted to warn others, and that they had Gemini write the post. The account is uncorroborated.

May 2025United StatesUnidentified video tool
At a sentencing hearing in May 2025 in Maricopa County Superior Court, Arizona, the family of a man killed in a 2021 road-rage shooting in Chandler played a video that combined real footage with an AI-generated likeness and voice of the victim delivering a script written by his sister, including statements of forgiveness addressed to the defendant. The judge said he loved the video, described it as genuine and referred to the forgiveness it expressed, then imposed the presumptive 10.5-year term for manslaughter, longer than the nine years the prosecutor had requested. The defense attorney appealed immediately. On 30 September 2026 the Arizona Court of Appeals upheld the conviction but vacated the sentence, holding that the AI video was not reliable and that the judge's consideration of it so prejudiced the defendant that the sentencing procedure was fundamentally unfair. The opinion says the record does not show precisely how the video factored into the sentence, and that there is no question it played a role. The case returns to the trial court for resentencing; as of 1 October 2026 no new sentencing date had been set.

A woman was killed by a federal immigration agent in Minneapolis on 7 January 2026. Mother Jones reports that an X user asked Grok to alter a photograph of the woman into a sexualized image and that Grok complied and published the result on X, citing a CNN correspondent's post and Grok's own replies, in which the chatbot said it had used sensitive content unintentionally and that the image may violate the 2025 TAKE IT DOWN Act. Mother Jones dates the request to Wednesday 7 January, while the correspondent's post is dated Thursday 8 January and the New York Times reports requests to Grok about the woman on Thursday. Rolling Stone and the Southern Poverty Law Center's Hatewatch describe the same episode. The woman was already dead when the image was made, so the death is context only and no source connects it to an AI system. No statement from relatives about the image was found. The record does not name the woman and describes the image only as a sexualized alteration.

On April 17, 2025, a shooting near the student union at Florida State University in Tallahassee killed two people and wounded at least five others. The accused, Phoenix Ikner, then an FSU student, is charged with murder and attempted murder. ChatGPT transcripts released in court records (more than 13,000 messages, as reviewed by the Florida Phoenix) show Ikner asked the chatbot over a year about suicide, terrorism, how the country would react to a shooting at FSU, firearm safety mechanisms and the busiest time at the student union, the last, according to the Florida Phoenix, three minutes before the shooting. Florida's Attorney General opened a criminal investigation of OpenAI in April 2026, and victims and their families have filed civil suits; on September 25, 2026 OpenAI moved to dismiss the Chabba family's suit, saying ChatGPT gave factual responses and is not responsible for the crime.

Eight victims were killed in Tumbler Ridge, B.C., on 10 February 2026, and the shooter died by suicide. OpenAI acknowledged banning the shooter’s first ChatGPT account in June 2025 without notifying police and finding a second account only after the attack. Families and survivors filed California lawsuits, followed by B.C. and its school board on 21 September. Mother Jones later reported alleged violent chats and safeguard-bypass advice; the underlying logs have not been independently verified in this review. OpenAI disputes the liability allegations. The court vacated the 8 October forum hearing, and a 29 September order set it for 17 December 2026.
