The BBC has apologised after sexual noises interrupted live television coverage of the FA Cup.
Moaning was heard while Gary Lineker presented the third-round replay between Wolves and Liverpool on Tuesday.
The football pundit later posted a picture of a mobile phone he said was "taped to the back of the set".
"We apologise to any viewers offended during the live coverage of the football this evening," the BBC said.
