The BBC says it's sorry after loud sexual noises disrupted its live sports coverage on TV

• A live BBC analysis of an FA Cup match was interrupted by loud sexual moans on Tuesday.
• Presenter Gary Lineker later said his team discovered the sounds came from a phone taped to the set.

The BBC has apologized after pornographic moans were heard while its presenters covered a soccer match live on air.

Soccer pundit Gary Lineker was presenting a replay on Tuesday evening of an FA Cup match between the Wolverhampton Wanderers and Liverpool when the sexual noises started playing.

"I don't know who's making that noise," Lineker said as he tried to keep a straight face. He then cut to fellow pundit and former striker Alan Shearer in the commentary box.

"It's toasty in this studio!" Lineker told his colleague. "It's a bit noisy as well, somebody's sending something on someone's phone. I think it's a joke, I don't know if you've heard it at home."

He, Shearer, analyst Danny Murphy, and Reading FC manager Paul Ince awkwardly continued their commentary as the noises kept playing at various intervals.

"Will you stop making those noises, Danny?" Lineker joked at one point in their analysis.

Lineker tweeted after the segment that the source of the moans had come from a phone taped to the back of the set.

"As pranks go, it was a good one. Credit to them, it was funny, I thought," Lineker said of the incident in an interview on "BBC Newsnight."

In response to the gaffe, the BBC said: "We apologize to any viewers offended during the live coverage of the football this evening."

A spokesperson for the broadcaster added that it is investigating the incident.

A prankster named Daniel Jarvis, who posts on YouTube under the moniker "Jarvo69 aka BMWJarvo," has since claimed credit for the prank. Jarvis, who on his channel describes himself as "The Greatest Prankster of all time," streamed a video on Tuesday evening of himself watching the BBC coverage indoors.

In the video, he appears to call the mobile phone attached in the studio just before the noises are played, laughing as he watches the pundits' reactions.

Insider was unable to independently verify the authenticity of his claim.

Jarvo69 aka BMWJarvo and the BBC did not immediately respond to Insider's requests for comment.
