West Midlands Police chief constable Craig Guildford has apologised to MPs for giving them "erroneous" evidence about the decision to ban Maccabi Tel Aviv fans, blaming the use of AI.
It comes on the day Home Secretary, Shabana Mahmood, is due make a statement to MPs after receiving a report on the decision to bar the Maccabi fans from attending a Europa League match against Aston Villa in November.
The force has been accused of misrepresenting the threat to justify advocating the exclusion of the Israeli club's fans from the match at Villa Park in Birmingham.
In a report to the Birmingham City Council Safety Advisory Group over whether to prevent supporters from attending the game, West Midlands Police referenced a match between the Israeli club and West Ham United that never happened.
Mr Guildford told the Commons Home Affairs Committee (HAC) in a letter that until Friday afternoon he believed the mistake was caused by using Google, when in fact it was the result of Microsoft Co Pilot.
He offered his "profound apology" for the error, but added: "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."
In the letter, Mr Guildford said he "became aware that the erroneous result concerning the West Ham v Maccabi Tel Aviv match arose as result of a use of Microsoft Co Pilot".
