The BBC has issued an apology after coverage of the Liverpool v Wolves match was interrupted by 'sex noises'.

In a Twitter post after the game began, Gary Lineker explained the origin of the noises with a snap of a taped-up mobile phone.

The presenter said: "Well, we found this taped to the back of the set. As sabotage goes it was quite amusing.”

As the noises began, the commentator was seen smirking between laughs and said: "It's toasty in the studio.

"It's a bit naughty as well.

"I think it's someone's setting something off on someone's phone."
