Dave Lee Travis, the former Radio 1 DJ and Top of the Pops presenter, was arrested yesterday (Thursday) by detectives investigating allegations of sexual abuse.
The 67 year-old was detained at his home in Leighton Buzzard, Bedfordshire, at 7.45am on suspicion of sexual offences as part of the Metropolitan Police's Operation Yewtree.
He is the fourth person to be arrested as part of the investigation, which began after scores of allegations were made against Jimmy Savile, the late presenter.
Scotland Yard's investigation is looking at three categories of alleged offences: those involving Jimmy Savile, those involving Savile and others, and those involving others.
A spokesman for the Metropolitan Police would not confirm the identity of the person arrested, but said he came under the "others" strand of the investigation. A neighbour of the former disc jockey confirmed that the broadcaster was being held in Aylesbury police station, Buckinghamshire. The neighbour visited the DJ's home to lend support to the broadcaster's wife, Marianne.
Travis made his name as a DJ on Radio Caroline, the pirate station, in the mid-1960s before joining Radio 1 in 1968.
He became one of the station's most established presenters, becoming known as the Hairy Cornflake when he took over from Noel Edmonds as presenter of the Breakfast Show in May 1978.
He also presented Top of the Pops between 1974 and 1984, but left the corporation in dramatic style in 1993, resigning live on air in protest at changes being made to Radio 1.
Since then he has worked for a number of commercial radio stations, most recently appearing on the Magic Network. Last year, Aung San Suu Kyi, the Burmese pro-democracy leader said Travis's music request show on the BBC World Service had given her a lifeline during her many years under house arrest. The Nobel Peace Prize winner said A Jolly Good Show, which was broadcast between 1981 and 2001, had made her world "much more complete". She met Travis on her visit to Britain in June.
There is no suggestion that allegations of paedophilia have been made against Travis, but two women have come forward in recent weeks claiming that he molested them during the 1970s and 1980s. One of the women, who was aged 17 at the time, alleged that Travis had invited her into his studio in 1977 and put his hand up her skirt.
Speaking last month, when the allegations surfaced, Travis said: "I categorically deny that there is any substance in either allegation and I'm genuinely surprised that allegations of this nature have been made. I totally refute any impropriety."
Travis also said he would be more than happy to speak to the police to clear up the matter.
