Derbyshire Police has pulled an officer from frontline duty after an investigation found he used AI to fabricate evidence in several cases. The force says the officer may have perverted the course of justice. No arrests yet, but the case is under police and Crown Prosecution Service review.

The inquiry follows the launch of PoliceAI, a national centre aimed at guiding law‑enforcement use of machine learning. Interim director Alex Murray noted crime and technology evolve quickly. Derbyshire’s case raises questions about oversight when officers exploit generative models to alter trial records without proper safeguards.

Police said early stages mean little detail is available, yet the incident signals a breach of ethical standards in digital evidence handling. If the Crown Prosecution Service finds sufficient proof, charges could follow. The incident underscores the need for clear protocols around AI‑generated content in investigations to prevent future misuse and protect public trust.

The removal of the officer and the ongoing probe set a precedent for how departments handle internal misconduct involving emerging tech. It also highlights the urgent demand for training and oversight frameworks that keep pace with AI’s rapid deployment in policing to ensure fair investigations.
