A man wanted by Interpol for terrorist offences has been advising Scotland Yard, it was reported.
The Times claimed Mohamed Ali Harrath had been advising the Metropolitan Police, the UK's biggest force, on countering Muslim extremism.
Tunisian-born Mr Harrath, 45, is listed as wanted on the Interpol website. Interpol is the world's largest international police organisation.
The site lists his categories of offences as counterfeiting, forgery, crimes involving the use of weapons, explosives and terrorism.
The Interpol website reveals that an arrest warrant for Mr Harrath was issued by Tunisia.
The Times reported that Mr Harrath had been appointed by Scotland Yard as an adviser to its Muslim Contact Unit on preventing terrorism.
Mr Harrath is reportedly the chief executive of the broadcaster, the Islam Channel, based in London.
The Met has so far refused to comment on the story.
