DJ Dave Lee Travis has been re-arrested over further allegations of sexual offences.
The 67-year-old was originally arrested by Operation Yewtree detectives investigating the Jimmy Savile abuse scandal in November.
He answered bail on Monday and was re-arrested in connection with further allegations made to officers working on Operation Yewtree.
A spokesman for Scotland Yard said a man in his 60s from Bedfordshire had been interviewed when he answered bail on Monday.
He said the man was "further arrested on suspicion of sexual offences in connection with further allegations made to Operation Yewtree".
In November Lee Travis denied any wrongdoing and said he did not want his name associated with "bloody evil" child abuse.
Speaking outside his home in Leighton Buzzard at the time, he said: "The point I want to make here is that none of the things I've been talking to the police about, or have talked to them about, is to do with children."
The Magic AM presenter was taken off air by the radio station's owners when the claims emerged.
