Police have raided three clubs - one of which is believed to be Newcastle United - as part of an ongoing investigation into alleged corruption in football.
City of London Police conducted the operations which they claim were 'totally independent' of Lord Stevens' ongoing Quest inquiry into the Premier League transfer dealings.
Search warrants were executed on the club premises and also two homes during the early hours of Monday morning.
A police spokeswoman said: "We can confirm that search warrants were served at three football clubs and the homes of two individuals in connection with corruption in football and its impact on owners and shareholders.
"This investigation is a totally independent inquiry. It has not been influenced or informed by the Quest inquiry in any way.
"As this is a live investigation, it would be inappropriate to comment further at this stage.''
