Moaning mobile phone plays out during BBC FA Cup coverage

Gary Lineker revealed the loud moaning noises heard during the BBC's live coverage of the FA Cup clash between Wolves and Liverpool were caused by a hidden mobile phone "taped to the back of the set".

The BBC presenter was previewing the third-round replay in a studio at Molineux alongside pundits Paul Ince and Danny Murphy when awkward and audible pornographic wails broke out in the background.

Lineker looked momentarily startled by the prank and struggled to keep a straight face thereafter as he cut to colleague and fellow former England striker Alan Shearer in the commentary gantry.

Lineker tried to laugh off the incident as the noise continued to blare out and said to Shearer: "Somebody's sending something on someone's phone, I think. I don't know whether you heard it at home."

Well, we found this taped to the back of the set. As sabotage goes it was quite amusing.
