Three people have been arrested by police investigating an alleged plot to blackmail Wayne Rooney and his wife, Coleen.

The couple accidentally left a camera at the MEN Arena, in Manchester, after the couple went to a Black Eyed Peas concert last year.

Despite a search of the concert arena’s VIP area after the gig in May, the camera could not be found and was not handed in.

Instead, photos of their son, Kai, which were stored on the camera, were allegedly offered for sale to a variety of newspapers.

Officers from British Transport Police (BTP), were later called in.

A spokesman said: “We are investigating an allegation of blackmail which was reported to us in September 2010.

“As a result of those investigations we have arrested three people – two men and a woman.

“They are currently on police bail pending further inquiries.”
