A former BBC producer has been arrested in connection with the inquiry into abuse claims made against Jimmy Savile.
Wilfred De'Ath, who is in his 70s, was held in Cambridgeshire at 07:15 GMT.
A Met Police spokesman did not confirm his name but said a man was arrested on suspicion of sexual offences and taken into police custody locally, before being bailed until December.
He added the man was held as part of the Operation Yewtree probe into claims Savile sexually abused young people.
Police believe the former BBC TV presenter and DJ, who died last year aged 84, may have abused as many as 300 people over a 40-year period.
Mr De'Ath once produced a Jimmy Savile radio show. Neighbours at his flat in Cambridge said detectives removed bags from the property.
A number of individuals are being investigated as part of the operation. These include people who allegedly carried out abuse with Savile as well as others who are suspected of abusing independently of Savile.
The Met said the latest arrest "falls under the strand of the investigation we have termed others".
Former pop star Gary Glitter was the first person to be arrested in connection with the Met's Savile abuse inquiry.
Glitter, 68, whose real name is Paul Gadd, was arrested on suspicion of sex offences and bailed until mid-December.
At the beginning of November police arrested entertainer Freddie Starr on suspicion of sexual offences.
He has denied claims made against him and was bailed after a number of hours of questioning.
