Barrowman sorry for radio flash

Barrowman plays Jack Harkness in Doctor Who spin-off Torchwood

Torchwood star John Barrowman has apologised for exposing his genitals during a live BBC Radio 1 broadcast.

"I was joining in the light-hearted and fun banter of the show and went too far," he said. "I was wrong to do this and it will never happen again."

The BBC has also apologised for the incident on Sunday's Switch show, which prompted one listener to complain.

"We do feel the programme overstepped the mark," it said, adding an apology was made at the end of the broadcast.

A spokeswoman also stressed that nothing untoward was screened online via the station's webcam.

Barrowman was chatting with hosts Nick Grimshaw and Annie Mac when he was asked about his predilection for exposing himself during interviews.

He responded by saying he was going to "get it out", amid laughter.

Barrowman said later: "I didn't take the whole thing out, but I got my fruit and nuts out."

In a statement issued on Monday, the I'd Do Anything judge said he appreciated "the great support" he had received from the BBC over the last few years.

He "would never intentionally do anything to undermine the integrity of the corporation," he continued.

"I apologise for any offence I have caused."

The show has now been taken off the BBC's iPlayer service.
