West Midlands Police cited a Microsoft Copilot-fabricated match to justify banning Israeli fans
West Midlands Police used Microsoft Copilot to generate intelligence for a risk assessment ahead of the Aston Villa vs Maccabi Tel Aviv Europa League match on November 6, 2025. The AI hallucinated a fictitious 2023 fixture between Maccabi Tel Aviv and West Ham United that never occurred, and this fabricated evidence was cited to justify banning all Maccabi Tel Aviv away fans. Chief Constable Craig Guildford initially denied AI use before admitting the error in January 2026, triggering an IOPC investigation and force-wide suspension of Copilot.

What happened
West Midlands Police used Microsoft Copilot to generate intelligence about Maccabi Tel Aviv fans ahead of their Europa League match against Aston Villa at Villa Park on November 6, 2025. The AI produced a hallucinated reference to a non-existent 2023 fixture between Maccabi Tel Aviv and West Ham United, which the force cited as evidence of previous fan trouble. Based on this fabricated intelligence, the force classified the match as high risk and banned all Maccabi Tel Aviv away fans from attending. Chief Constable Craig Guildford initially told the Home Affairs Select Committee on January 6, 2026 that AI was not used, before admitting in a letter on January 14, 2026 that the erroneous information came from Microsoft Copilot. The Home Secretary called for Guildford to resign, the force suspended Copilot force-wide, and the IOPC opened an investigation.
What broke inside the model
- 01 · TriggerA user asks for a fact, a citation, or a figure.
- 02 · Model stepThe model writes a fluent, confident answer.
- 03 · Control gapNothing ties the claim back to a real source.
- 04 · FailureA fabricated fact ships as if it were verified.
- 05 · ConsequenceThe false claim reaches a customer, a court, or the public.
Confidence holds, and even spikes, as the claim detaches from any source.
Microsoft Copilot generated a confident but entirely fabricated reference to a 2023 match between Maccabi Tel Aviv and West Ham United that never took place. The police force failed to verify the AI-generated intelligence before incorporating it into a formal risk assessment, treating the fictitious match as real evidence of previous fan disorder. The initial denial of AI use compounded the failure, delaying accountability for approximately two months.
