A "petrified" woman has told how she thought she was going to be raped by DJ Dave Lee Travis when she was 15 at a Showaddywaddy concert, a court heard.
The alleged victim, who cannot be named for legal reasons, said the former BBC Radio 1 DJ became "frisky" with her after she was invited into his caravan at the gig on a farm in the late 1970s.
In a videoed police interview played at Southwark Crown Court, the woman said she was talking about music with Mr Travis inside the caravan when he offered to sign her poster.
He then "lunged forward", she said.
"He started snogging my face off," she said. "He got his hand up my shirt and pulled my bra up.
"He was just all over my boobs. He was so heavy I was trapped in the seat. I could not get up.
"I thought he was going to rape me."
The woman told police Mr Travis then "suddenly" got up and told her to leave before she hitch-hiked home.
Asked how she felt during the incident, she replied: "Petrified."
Mr Travis, whose real name is David Patrick Griffin, is charged with 13 counts of indecent assault dating back to between 1976 and 2003, and one count of sexual assault in 2008.
The court had earlier heard from other women who said they had been abused by Mr Travis.
One witness, now a head teacher, said she "recoiled" after being indecently assaulted by the DJ at a student gig in Nottingham at the height of his fame.
A former colleague also described how, two decades later, Mr Travis reduced her to tears after allegedly subjecting her to a "horrible" assault at radio station premises.
The 68-year-old, from Buckinghamshire, is accused of assaulting 11 women, one of whom was 15 at the time of the alleged crime.
He denies all the charges.
