Derbyshire Police remove a detective from frontline duties and open a criminal investigation over alleged use of AI to create evidential material
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.
