TL;DR
The Independent Office for Police Conduct said on 22 October that it is investigating a Derbyshire Constabulary detective over alleged misuse of AI while working on criminal cases. The officer is accused of using Microsoft Copilot to write policy decisions, weigh up and handle risk, and justify choices, and of entering sensitive operational and personal case data. The detective has been served with a gross misconduct notice.
How the case reached the watchdog
Derbyshire Constabulary referred the matter itself on 23 June, after an internal review raised concerns that the officer’s AI use had gone beyond what the force allowed. The IOPC reviewed the referral and decided to run the investigation independently rather than leave it with the force.
According to the IOPC, the force cleared Copilot for officer use in May 2025, with guidance that it could help write reports and summarise material. Its conditions barred officers from entering any personal, operational or otherwise sensitive material into the tool.
Emily Barry, the IOPC’s director of engagement, called the claims “serious allegations” and said the inquiry would examine how the officer used Copilot from May 2025 to June 2026, then judge whether police professional standards were broken.
The bigger picture
The watchdog has been here before. Earlier this month it warned that officers risk ‘accidental’ AI misconduct.
The Derbyshire case shows where the line sits in practice. Using a general-purpose assistant to tidy a report was permitted; using it to reach and justify decisions about risk, with live case data, is what is alleged to have crossed it.
Looking forward
No finding has been made; the investigation will assess whether any professional standards were breached. For UK organisations rolling out workplace assistants, the episode is a useful test of whether written conditions on AI use are enough without technical controls behind them. In our view, a rule against pasting sensitive data into a chatbot is only as strong as the means to detect breaches of it, and here it took an internal force review to bring the alleged misuse to light.
