A headteacher has told a court that she "recoiled" and ran home after being indecently assaulted by DJ Dave Lee Travis at the height of his fame.

The woman, then a student in Nottingham in the 1980s, said the DJ assaulted her after inviting her on board his hi-tech campervan when he was booked to appear at a university gig.

Her evidence came after a junior radio worker told Travis's trial that she was subjected to a "horrible" assault by the "grandad"-like figure two decades later.

Travis, who was nicknamed "The Hairy Cornflake", was appearing on the BBC Radio 1 Breakfast show when he allegedly assaulted the student at Trent Polytechnic, London's Southwark Crown Court heard.

Giving evidence from behind a curtain, the alleged victim said she was asked to guard the vehicle because: "He said he didn't trust Nottingham - it was 'a bit of a dive' and he wanted some guards."

She said a few "guards" were given a badge, which the woman said she wore on her top.

She said: "He made a joke. He took the badge, lifted it, touching my breast ,and made a joke about the badge, saying 'Oh, you're securi-t***y'.

"I was embarrassed, a bit shocked. I thought this is obviously the world I belong in and not something I had experienced before. I recoiled."

The witness said she was later summoned into the campervan as a "thank you" from the entertainer, which she assumed would result in being given a free Radio 1 T-shirt.

"I was an innocent girl," she said. "It never entered into my head something was going to happen."

The woman said she became "rigid with fear" as Travis put one hand on the wall and one around her.

"He came towards me and touched me. I could feel his tongue, he just relaxed. I went under his arm and ran.

"I was upset and I felt stupid. I thought I was lucky 'cos I had escaped. It felt so smooth, so slick, so rehearsed. I thought 'Gosh, I can't be the only one this has happened to'."

Travis, whose real name is David Patrick Griffin, is on trial charged with 13 counts of indecent assault dating back to between 1976 and 2003 and one count of sexual assault in 2008.

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.

Travis groaned from the dock at points during the witness's evidence.

She told the court that, when she was first given a tour of the van, there were two young women inside wearing "short skirts and low tops".

They were both adults but "quite young", she said.

The witness, who is now a headteacher, said she would not have come forward had she not seen Travis on television after he was arrested in the wake of the Jimmy Savile investigation.

"I remember saying to my husband 'It will be Dave Lee Travis next, he's got to be next'," she said. "I'm a tenacious person, I have a moral duty. I felt duty-bound."

Earlier, a former Chiltern Radio worker told the court she was "gutted" when the former Radio 1 presenter groped her after allegedly hugging her from behind and blowing a raspberry on her face.

The woman, who cannot be named for legal reasons, said she ran to the toilet and had tears in her eyes after the incident.

She said: "He came in and came up behind me and hugged me from behind and blew a raspberry on my face.

"It was just a bit too close. But then his hand was on that bit of your tummy below your belly button. No-one ever touches you there, it is quite personal. When he did that I kind of went to shrug him off."

The witness said that as Travis went to move his hands away, he did so "deliberately and brushed over my breast".

She said she went to the toilet and thought: "Your eyes have filled up with tears."

She added: "I felt really weird. I was confused because I knew it felt horrible."

The woman said she initially saw him as a "friendly grandad-type", who gave bear hugs.

But the woman, who was in her 20s when she worked at Chiltern Radio in the same building as Classic Radio DJ Travis, said her opinion of him changed after the alleged assault.

She said: "I knew who he was because my dad was a big fan. That's why I knew who he was.

"I pretty much avoided him after that (alleged assault)."

The witness said she did not complain at the time because she found the alleged assault "very embarrassing".

"I think you're always not sure if something is bad or not," she said. "It was my first job. I was young. I enjoyed my job. I didn't want that kind of discussion to happen."

Stephen Vullo, defending Travis, told the court that his client did not remember the alleged incident.

Earlier, Chiltern Radio employee Simon Cliffe told the court that he was aware one of Travis's alleged victims, who worked at the station, had felt "uncomfortable" around the DJ but only knew of one formal complaint.

Asked by Mr Vullo whether the complaint was because his client had been "overly tactile", he replied: "It was probably stronger than that. Maybe an invasion of privacy or an invasion of space."

Mr Vullo asked whether Travis was "well-liked" at the station.

Mr Cliffe replied: "I think he was well-respected. He was quite a bubbly personality. There were some who liked him, yes."

Travis's former managing director at Classic Gold, Colin Wilshire, said he was aware of a complaint about the DJ by a female member of staff.

Referring to his former colleague as DLT through the testimony, Mr Wilshire said a woman complained that Travis "touched her on the leg... legs".

He said Travis was told to "stay away" from the woman and her office.

Mr Wilshire said a complaint against Travis was raised at a board meeting. But no "mark" was left on his HR file, he said.

Mr Wilshire said he did not speak to the witness but called the veteran DJ into his office and explained the complaint.

He said Travis replied that he "didn't intend to upset her" and that "wasn't his intention".

However, the DJ immediately appeared to dismiss orders not to enter the alleged victim's office, the court heard.

Mr Wilshire said: "I hauled him (Travis) back into my office and said 'I need to talk to you about this'.

"I wanted to make sure he understood what was going on. He had clearly not listened to what I wanted him to do.

"I actually just wanted him to go home at that point because there was a lot of anger. He was flustered, he was very angry."

Travis was ordered to go home for the day, the court heard.

Questioned by Mr Vullo, Mr Wilshire said Travis had left Classic Gold following "artistic differences" over playlists and his shifts, and not due to the complaint from a female colleague.

Mr Wilshire said he did not perceive the complaint as being "an allegation of serious sexual assault" at the time.

Mr Vullo asked Mr Wilshire how the prosecution's description of Travis as a "determined sexual predator" compared with the man he knew.

"It was at odds with how I thought he behaved generally," he replied.
