An apparent error by Microsoft’s Copilot is roiling a UK police scandal.
On Monday, West Midlands Police chief constable Craig Guildford wrote to a Parliamentary committee that his officers did not catch a hallucination by Microsoft’s AI tool when they were preparing their security recommendations for a soccer match between Maccabi Tel Aviv and Aston Villa on November 6.
Ultimately, fans of Maccabi Tel Aviv were barred from attending the UEFA Europa League fixture, a decision that sparked a torrent of criticism reaching as high as Prime Minister Keir Starmer.
The episode highlights the importance of all workers verifying AI output as the technology’s adoption expands. A spokesperson for Microsoft said it could not replicate the results Guildford said the department received.
“Copilot combines information from multiple web sources into a single response with linked citations. It informs users they are interacting with an AI system and encourages them to review the sources,” the spokesperson said in a statement to Business Insider.
Guildford said that Microsoft Copilot provided false information about a game between Maccabi Tel Aviv and West Ham United, a different Premier League squad. That game never happened, but the details were used to inform a decision that led to the police force’s decision to deny Maccabi Tel Aviv fans entry to the game against Aston Villa.
On Wednesday, Home Secretary Shabana Mahmood told Parliament that she had lost confidence in Guildford.
In the letter, Guildford apologized to the parliamentary committee investigating the matter because he had testified that AI was not used by the force in preparing their recommendations. He had previously said a Google search provided the inaccurate information.
“I had understood and been advised that the match had been identified by way of a Google search in preparation for attending HAC. My belief that this was the case was honestly held, and there was no intention to mislead the Committee,” he wrote.
According to the BBC, more than 700 police officers were deployed ahead of the game. Multiple protests occurred outside the stadium. In November, West Midlands Police said they had classified the match as “high risk.”
In an October statement, the police force had said its decision was based on “current intelligence and previous incidents, including violent clashes and hate crime offences” that occurred during a separate game involving Maccabi Tel Aviv in Amsterdam the previous year.
As Israel’s oldest soccer team, Maccabi Tel Aviv has spent decades trying to break through at the top levels of European soccer. The Europa League is UEFA’s second-highest level of competition for continental teams, behind the Champions League.
