Former BBC DJ and music producer Chris Denning, 75, has pleaded guilty to 21 child sex offences committed between 1969 and 1986. When sentenced on October 6 at Southwark Crown Court, this will be on top of his present serving of a 13-year sentence for a previous 24 offences he had committed on children aged 9 to 16 between the 1960s and the 1980s.

Part of the original DJ line-up upon the BBC Radio1 launch in 1967, Surrey Police said in a statement:

“Denning, who was looked up to and sometimes idolised by many young people, has used his status to prey on innocent children which he has now admitted to,” said Detective Chief Inspector Jo Hayes.

This continues the extensive enquiry into the Walton Hop Disco, Walton-on-Thames, where several names have been arrested into the enquiry of offenses between the years 1958 and 2001.

When Denning was initially jailed in 2014, police issued a statement about this operation entitled Operation Arundel (which also jailed Jonathan King in 2001 for indecent assaults).

“The force conducted a previous investigation involving allegations of historic sexual abuse by high profile individuals linked with the Walton Hop disco under the name Operational Arundel, resulting in several convictions for sexual offences.

“Material relating to this investigation has been shared with [the Metropolitan Police’s] Operation Yewtree as part of their ongoing enquiries.

“In January 2014, Surrey Police commissioned an independent review of Operation Arundel by Merseyside Police to ensure all available lines of enquiry had been fully identified and exploited.

“This review has now been completed and a number of actions have been identified, which are now being progressed by Surrey Police as Operation Ravine.”

Sentencing will occur on October 6 at Southwark Crown Court by the same judge who sentenced him in 2014.
