A Derbyshire Constabulary officer is under criminal investigation after allegations that the officer used AI to generate “evidential material” used in criminal cases. Police say they have launched the probe following an allegation of suspected perverting the course of justice. Several outlets report that the officer is suspended from frontline duties while the matter is examined, including work involving the Crown Prosecution Service (CPS). The CPS is described as engaging with defence lawyers and the courts regarding potentially affected cases.

Coverage characterizes the allegation as involving AI-generated material being used in a number of cases, rather than a single incident, though specific cases and details are not provided in the summaries. The reporting also notes that this is presented as the first known allegation of AI misuse by a police officer in a criminal case in the UK, while pointing to a prior incident in which West Midlands police relied on AI-generated material connected to a football-related intelligence matter.

Across sources, the central points are the existence of a Derbyshire police investigation, the nature of the allegation involving AI-generated evidence, and the involvement of the CPS and legal process to identify and address cases that may be affected.
