The Hayes-born former Radio 1 DJ Chris Denning has pleaded guilty to 21 child sex offences stretching back to the 1960s after police investigated incidents at a youth disco.

The 75-year-old has admitted to abusing a total of 11 children between 1969 and 1986, some as young as eight.

Denning pleaded guilty at Southwark Crown Court to 21 offences, including indecent assault of men and boys as well as inciting boys under 16 and 14 to commit acts of gross indecency.

However, he denied three counts of indecent assault.

Police investigated teen disco

Surrey Police carried out an investigation – Operation Ravine – into alleged sexual offences linked to the Walton Hop Disco for teenagers which ran from 1958 until 2001.

Denning, who was one of the founding presenters of Radio 1 , appeared in court on Monday (August 22) wearing a red T-shirt, tracksuit bottoms and a pair of glasses.

He is set to be sentenced at the same court on October 6 by Judge Alistair McCreath.

Denning also has a string of previous sex offences conviction for abusing young boys and is currently serving a 13-year sentence.

His previous offences are against 24 victims in the 1960s through to the 1980s.

'He has a very long record of offences against young boys'

Judge Peter Testar said: "Judge McCreath sentenced this defendant in November 2014.

"It must make sense, Judge McCreath having passed that sentence, for him to sentence this man for these offences because the question which must arise is the relationship between any sentence passed today and any sentence passed then."

The three charges he pleaded not guilty to were ordered to lie on the file.

Prosecutor Jonathan Polnay said: "He has a very long record of offences against young boys.

"Given the very long indictment he has pleaded guilty to, we take the view that these counts would not make a difference to sentence."

Denning used drugs and alcohol

It was revealed Denning used drink and drugs to groom his young victims.

Judge McCreath told Southwark Crown Court at the time the abuse was "inappropriate and depraved".

He added: "It is not to be forgotten that all of this suffering was inflicted by you without thought for anything other than your own selfish pleasure."

Denning was said to have "used the allure of the record industry and celebrity" to sexually assault the boys - including one allegedly at his Savile’s house.

The fiend took young boys out to watch Top Of The Pops recordings and introduced them to a string of stars including the disgraced late DJ Savile.
