Event date unknownUnited KingdomUnidentified chatbot
Derbyshire Police said in June 2026 that it had launched a criminal investigation into an allegation of perverting the course of justice after the alleged use of AI systems by an officer to create evidential material in a number of cases, and that the officer had been removed from frontline duties; no arrests had been made. The Crown Prosecution Service said it was engaging with defence teams and the courts in appropriate cases. Scottish Legal News, citing sources familiar with the matter, reported that the detective allegedly used an AI chatbot to prepare documents including victim impact statements and case summaries for prosecutors. It also reported that a number of rape convictions were being reviewed. In October 2026 the head of the Independent Office for Police Conduct referred to the case when warning that AI mistakes could lead to a mistrial. The officer is not named, the AI system is not identified, and the allegations have not been tested.

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.

Event date unknownEstoniaUnidentified AI writing tool
According to Delfi Ärileht and ERR (both 26 June 2026), complainants who went to the Tallinn Administrative Court to contest a felling permit sent the court a document that cited scientific work on the effects of clear-cutting. The court found that the Estonian scientists named in the references do not exist and that the studies could not be found. It asked how the document had been produced, gave the complainants the chance to submit the cited works, and warned of a fine for attempting to mislead the court. The complainants replied that using AI is not forbidden and that they had not meant to mislead the court. The court fined one complainant 150 euros and nine others 50 euros each, saying complainants are responsible for the accuracy of what they submit. Delfi Ärileht reports that the Tallinn Circuit Court agreed and that the Supreme Court declined the case that week, so the fines are in force. No report names the tool or says which complainant used it.

Event date unknownEvent location unknownUnidentified image and video tool
On 14 September 2026 the Manhattan District Attorney's Office announced that it had seized, under a court order, 12 domain names of websites it says were used to disseminate, publish and sell non-consensual 'deepfake' videos, and said its investigations were ongoing. The office alleges that people under investigation used AI image and video creation tools to turn existing photos and videos of approximately 1,200 real people, overwhelmingly women and mostly public-facing figures, into sexual images and videos that were then sold. The 1,200 figure is the office's estimate and is not a documented count. WIRED reported that it had observed seizure notices on several of the sites in the days before the announcement and quoted researchers who described the videos as pornographic films manipulated to show the targets' faces, many apparently reposted from the defunct MrDeepFakes site. When the depictions were made and published is not established; one site claimed to have been online since 2018.
