A man aged in his 80s has been interviewed by detectives investigating the Jimmy Savile abuse scandal, Scotland Yard has said.
The suspect, from Berkshire, was questioned after attending police premises in south London by appointment around noon on Thursday.
Shortly after 5pm the force said that he had left the building.
He is being treated as part of the investigation that does not directly relate to Savile, said the Metropolitan Police.
The force also revealed that officers had searched an address in Berkshire on Saturday.
Before Thursday, four arrests had been made as part of the national investigation into alleged sexual offences by Savile and others.
Gary Glitter, comedian Freddie Starr, DJ Dave Lee Travis and a man in his 70s have been arrested and bailed as part of the probe.
Scotland Yard is leading the inquiry and has said officers are currently dealing with around 450 potential victims, the vast majority of whom claim they fell prey to Savile.
