Former DJ Dave Lee Travis has been arrested by police investigating the Jimmy Savile child abuse scandal, Sky sources have said.
The one time Radio 1 star and former presenter of Top Of The Pops is reportedly being questioned on suspicion of sexual offences.
He was arrested by detectives from the Metropolitan Police's Operation Yewtree at his home in Leighton Buzzard, Bedfordshire, at 7.45am, according to sources.
It is understood that the allegations do not directly involve Savile and are classed under the strand of the investigation termed "others".
The Metropolitan Police force is leading a national investigation into abuse allegations made against disgraced Jim'll Fix It presenter Savile.
So far, around 450 potential victims have come forward and 200 allegations of sexual assault have been made.
Officers are looking at three strands within their inquiry - claims against Savile, those against Savile and others, and those against others.
Most of the "others" allegations have been made against people associated with the entertainment industry.
Former glam rock star Gary Glitter, comedian Freddie Starr and a 73-year-old man have already been arrested and bailed in connection with the investigation.
A 1977 episode of Top Of The Pops featuring Mr Travis was due to be shown on BBC4 on Thursday night but has been pulled.
A BBC spokesman said: "In the light of today's news, we have postponed tonight's Top Of The Pops.
"In its place we are showing next week's edition of TOTP presented by Kid Jensen."
Last month Mr Travis vigorously denied allegations that he groped two women while in BBC studios.
