A police officer in Derbyshire is under criminal investigation for allegedly using artificial intelligence systems to generate evidential material in multiple cases [1, 2]. The officer has been removed from frontline duties pending the outcome of the inquiry [1, 2]. Authorities say the officer is suspected of perverting the course of justice but have disclosed no further details about the individual or specific allegations [1, 2].
No arrests have been made so far in connection with the investigation [1, 2]. Derbyshire Police is working closely with the Crown Prosecution Service (CPS) on cases potentially impacted by the inquiry [1, 2]. The CPS is engaging with defense teams and courts in cases related to the investigation but declined to provide further comment [1, 2].
This is the first known case in the UK of a police officer being criminally investigated for allegedly using AI in evidential matters [1]. The probe follows a recent warning from the Police AI Centre, which cautioned some forces to stop using AI for court statements due to reliability concerns [1].
The investigation came to light during the week of June 10–12, alongside the launch of the Police AI Centre [1, 2]. Earlier in April 2026, the Metropolitan Police conducted an investigation into hundreds of officers reportedly using AI software by Palantir to identify misconduct [1].
Alex Murray, interim director of Police AI, said at the centre’s launch, "Crime and technology are evolving rapidly. Policing must keep pace by adopting AI responsibly to catch criminals and keep people safe" [2].
The investigation remains in its early stages. Authorities have yet to reveal further details or timelines for the outcome. Meanwhile, Derbyshire Police and the CPS continue their cooperation as inquiries progress [1, 2].
