Former BBC Radio 1 DJ Chris Denning has been arrested under Operation Yewtree, it has been revealed.
The 72-year-old was questioned on Monday as part of the police inquiry set up after the Jimmy Savile scandal.
Mr Denning, who lived in Poole and once owned a shop in Parkstone, faces allegations unrelated to Savile.
He is the 13th person held as part of the enquiry. He has been bailed until July.
Of the suspects, only PR consultant Max Clifford and David Smith, a driver who used to work for the BBC, have been charged.
Ex-BBC producers Ted Beston and Wilfred De'Ath and a 65-year-old man who has not been named were released without charge.
Eight others, including Gary Glitter, Freddie Starr, Dave Lee Travis, Rolf Harris and Jim Davidson, remain on police bail.
