A fourth man has been arrested as part of an investigation into allegations of historical child sex offences involving former music mogul Jonathan King.
The 74-year-old was held by Surrey Police, which is looking into claims linked to the Walton Hop Disco in Walton-on-Thames.
King and two other men were arrested in September concerning the allegations of offences committed against boys under the age of 16.
The investigation, called Operation Ravine, was launched in late 2014 to look into child sex crimes linked to the Walton Hop Disco, following a review by Merseyside Police into a previous Surrey Police investigation that was entitled Operation Arundel and which was launched in 2000.
King, a former chart-topping star and TV producer, worked on BBC shows including No Limits and The Great British Song Contest.
