Polish outlets report YouTube videos falsely announcing the deaths of a TV presenter and the First Lady with AI-generated hospital-bed images; reported to NASK

Polish outlets reported on 4 October 2026 that a YouTube channel published videos whose titles and thumbnails falsely announced the deaths of television presenter Omenaa Mensah and of First Lady Marta Nawrocka, each shown in a hospital bed. Plejada describes the Mensah thumbnail as a graphic generated with artificial intelligence; Fakt describes the Nawrocka thumbnail as an AI-generated photo with a caption suggesting something terrible had happened to her. Mensah's husband, InPost founder Rafał Brzoska, posted on 3 and 4 October that his wife was alive, that one channel had been 'killing off' dozens of well-known people for weeks, that the matter was reported to NASK and the channel blocked, and that the videos were secured for the National Prosecutor's Office with a request for an investigation. He also wrote to President Nawrocki about the First Lady video. Neither depicted woman has commented publicly in the inspected sources; no deceived viewer or financial loss is reported.

Portland, Oregon: an anonymous social-media account posted 17 racist and anti-immigrant images targeting David Douglas High School football players and their coach, some digitally altered including with AI, from 22 September 2026; the school reported content to Portland police

David Douglas High School in Portland warned families in a statement reported on 28 September 2026 about social-media posts targeting its students, athletes, coaches and staff, saying some images and videos had been digitally altered, including with AI, and did not accurately represent those depicted; it reported some of the content to the Portland Police Bureau. KATU, which reviewed the account, reports 17 posts using racist, anti-immigrant and religious stereotypes against football players: one image shows a Latino player in a sombrero being detained by people labelled as ICE agents, another shows a player in a head covering with what appears to be a fake explosive vest, and a Black player is depicted beneath a caption referring to George Floyd. The head coach said students were hurt, and that one student texted him over the weekend after seeing one of the posts: 'Coach, this is terrible. What do I do?' The account references Rex Putnam High School, whose team David Douglas played on the Friday before the report; which along with its district says it has no connection to it. Who runs the account and which images were AI-generated are not reported.

Logroño: the Guardia Civil investigates a 14-year-old who took photographs of nine underage classmates from their public social-media profiles, used AI tools to strip and sexualise them, and uploaded the fake images to an adult pornography website under a profile describing them as girls from his school made with AI, organised in folders with each girl's personal details; the images reached about 40,000 views before removal (reported 14 July 2026)

On 14 July 2026 Spain's Interior Ministry published a Guardia Civil release stating that a 14-year-old from Logroño was under investigation as the presumed author of offences of discovery and disclosure of secrets, corruption of minors and child pornography. Investigators from the technology investigation team (EDITE) and Equipo@ found that he knew all nine victims, all minors and classmates, followed them on social media, took their photographs from the public content of their profiles without consent, and used artificial-intelligence tools to manipulate the images, digitally undress and sexualise them. He uploaded the fake pornographic material to an adult pornography website, created a profile there describing the content as girls from his school made with AI, and organised it in individual folders with each victim's personal data, which the Guardia Civil says made the girls recognisable and multiplied the emotional and social harm. Before the content could be removed it had reached about 40,000 views, amplifying the harm to the nine girls' privacy within hours. The proceedings were passed to the juvenile prosecutor under the juvenile criminal responsibility law; the release notes that parents or guardians are jointly liable for moral damages. Diario de León (Europa Press, 26 July) placed the case in a series of Spanish school cases since Almendralejo in 2023 and, unlike the release, described the minor as having been arrested.
