A man in his 80s is being interviewed by detectives investigating the Jimmy Savile abuse scandal.

The suspect, from Berkshire, is being questioned after attending a south London police station by appointment.

He is being treated as part of the investigation that does not directly relate to Savile, the Metropolitan Police said.

Four arrests have already 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, reported to be former television producer Wilfred De'Ath, 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 of Savile.
