The Federal District Civil Police (PCDF) in Brazil say a criminal group ran fake online donation campaigns that used images of elderly people, children and seriously ill people, and used artificial intelligence tools, including deepfakes, to make fake videos with the images of the singer Gusttavo Lima and the Catholic priests Marcelo Rossi and Fábio de Melo. The posts circulated on social media and sent people to pages imitating legitimate charity appeals; the money went to bank accounts the group controlled. Police say one company linked to the group received 215,575 transactions totalling about R$9.8 million between 13 October and 26 November 2025, mostly of R$30 and R$50, and that the number of transactions does not necessarily match the number of victims. On 28 October 2026 the PCDF launched Operação Cáritas with six preventive arrest warrants and search warrants in the Federal District and four states; five suspects had been arrested by the time of most reports (g1 reported six). How the police established that the videos were AI-made is not disclosed, and no response from the people depicted is reported.

A 12-year-old girl in Vitória da Conquista, in the south-west of Bahia, Brazil, was threatened from 14 October 2026 by a 15-year-old who said he had intimate images of her and demanded money not to post them on social media. Frightened, she secretly took R$8,300 from money her father kept and handed it over; the suspect then demanded a further R$10,000. According to the Bahia Civil Police, its investigation found that the image used in the threats had been produced with artificial intelligence to simulate intimate content of the girl. On 23 October police identified the 15-year-old and three other adolescents aged 14 to 16 as suspects, recovered R$6,300 and an electric bicycle bought with part of the money, and returned the money to her father. The police opened a juvenile offence procedure and sent it to the Childhood and Youth Court. How police established that the image was AI-made is not disclosed.

A woman in Porto Alegre, Brazil, saw an online video in which the model Gisele Bündchen appeared to promote a free skincare kit, paid the R$44.57 shipping fee and received nothing. Her police report, registered on 4 August 2024, led the Rio Grande do Sul Civil Police to Operation Modo Selva. On 1 October 2025 police executed 26 court orders in five states against a group they say used deepfake videos of celebrities, including Gisele Bündchen and several TV presenters, in fake product promotions; four people had been arrested by the time of the reports. The investigating delegate said the criminals had created a deepfake of the model's image and voice. Police say the scheme moved at least R$20 million, and assets worth up to R$210 million were frozen. The model thanked police for finding criminals who use artificial intelligence for online scams. No charge or trial outcome has been reported since.

In late October 2023, fake nude images of girls at a private school in Rio de Janeiro circulated in messaging groups and on social media. Families said pupils in years 7 to 9 had used an artificial intelligence tool to put the faces of pupils aged 14 to 16 onto photos of naked bodies. The school sent parents a notice about pupils using AI to make intimate photo montages and said disciplinary measures would follow. The Rio de Janeiro Civil Police child-protection unit (DPCA) opened an inquiry; its head said the pupils were suspected of making fake nudes with AI and that more than 20 victims had been identified, including girls from other schools. A mother said the girls were having anxiety attacks and crying. The inquiry was placed under seal because minors were involved; its outcome is not known.

In early September 2026 a private school in Jaú, in the interior of São Paulo state, identified the circulation of fake intimate images of a female classmate made with artificial intelligence and contacted the families. According to the police report described by the press, eight ninth-grade boys, all aged 15, kept a WhatsApp group in which they used digital programs to manipulate images of the student so that she appeared unclothed. The school suspended the eight and informed the girl's parents. The father of one of the boys checked his son's phone, found the files and took the boy and the phone to the police to register a report; the girl's parents also registered a police report. The São Paulo Public Security Secretariat said the Civil Police are investigating a 15-year-old for dissemination of child pornography and defamation that occurred on the morning of Thursday 3 September. The school said the content originated on a private platform outside the school environment and that it had adopted protective and welcoming measures for the student and opened an internal inquiry. The AI tool used is not named. The students are minors and are not named in any report.

On Monday 10 August 2026 a digital influencer from Picos, in the centre-south of Piauí, began negotiating a car advertised online for sale in Fortaleza (Ceará), where an uncle of his lives, and asked the sellers to take the car to the uncle so he could inspect it. On Tuesday 11 August a contact using a different number but the uncle's photo sent him audio messages in a voice identical to his uncle's, generated with artificial intelligence, saying the car was in good condition and telling him to make the bank transfer. Believing he was speaking to his uncle, he transferred the money; when he then called the uncle's real number he learned he had been defrauded. The loss exceeded R$56,000, money he says he had saved for years. He registered a police report on 11 August; the Piauí property-crimes unit (Depatri) is investigating and he is seeking a refund from the banks. The account is the victim's own, reported by G1 Piauí on 13 August 2026 from his social-media posts and an interview; the police unit did not respond to G1 before publication.
