Derbyshire detective under IOPC investigation over alleged inappropriate use of AI in criminal cases

The Independent Office for Police Conduct (IOPC) is carrying out an independent investigation into a detective from Derbyshire Constabulary. It concerns an allegation that the officer used artificial intelligence inappropriately during criminal investigations.

What the allegations are

Derbyshire Constabulary referred the matter to the IOPC voluntarily on 23 June. The force had first carried out an internal review of how the detective used AI. Concerns emerged that the use may not have complied with the guidance and conditions set by the force.

According to the IOPC, the officer is alleged to have used AI to create policy decisions, to assess and manage risk, and to justify decision-making. It is also alleged that sensitive operational and personal data relating to cases was entered into the tool.

The IOPC decided the matter required investigation and that it should carry it out independently. The officer has been served notice that they are being investigated for alleged gross misconduct. These are allegations at this stage, not findings.

Rules on using Copilot

IOPC Director of Engagement Emily Barry said Derbyshire Constabulary authorised officers to use Microsoft Copilot in May 2025. It was meant to help with work such as drafting reports and summarising information. Its use came with conditions, including a ban on entering operational, sensitive or personal data into AI.

IOPC investigators will analyse how the detective used Copilot between May 2025 and June 2026. They will also assess whether police professional standards may have been breached. Ms Barry described the allegations as "serious" and said they should be investigated thoroughly and independently.

What this means for you

The case does not change any rules and has no direct effect on residents' rights. It does show that UK police use AI tools, and that their use is governed by internal rules and oversight. This applies in particular to the protection of personal data in cases. The outcome of the investigation is yet to be known.
