Dave Lee Travis described as 'opportunist' sex offender 14 January 2014 Last updated at 14:29 Dave Lee Travis arriving at Southwark Crown Court Former BBC Radio 1 DJ Dave Lee Travis was an "opportunist" sex offender who targeted "vulnerable" young women, a London court has been told. The court heard the alleged offences took place in work settings, including pantomimes, openings and prize-givings. One young woman, aged 19, had been "assaulted live on Top of the Pops" in 1978, prosecutor Miranda Moore QC said. Mr Travis, 68, whose real name is David Griffin, denies 13 counts of indecent assault and one of sexual assault. "The offences vary in gravity," Ms Moore told Southwark Crown Court. All are sexual in nature involving unwanted contact by this defendant on much younger women, both over clothing and under clothing. Operation Yewtree One woman, who was an 18-year-old BBC clerk, alleges an assault in a BBC radio studio. She went to the Daily Mail in 2012 after she felt nothing was being done by the BBC, the court heard. The youngest alleged victim, who was 15, claims she was attending a Showaddywaddy concert in 1978 at a farm in Gloucestershire, where the defendant invited her in to his trailer for a drink. After discussing music, Mr Travis then commented on the girl's breasts, before lifting her top over her head and pulling down her bra to expose her breasts, Ms Moore told the court. Standing at the front of the dock, close to the glass, Dave Lee Travis listened intently as the court clerk read out the indictment. Hands clasped in front of his light brown jacket, the DJ followed the proceedings with the aid of a hearing loop - the acoustics at Southwark Crown Court are notoriously poor. After the charges had been set out, and the jury told that he had pleaded not guilty, the 68-year-old sat down as Miranda Moore, for the prosecution, outlined the case. Occasionally he glanced downwards or shook his head, but mostly he was focused on the courtroom in front of him and the 12 jurors who will eventually determine his fate. The woman claims she was then pinned to her seat. "In her words, she thought he was going to rape her," Ms Moore said. Mr Travis was arrested as part of Scotland Yard's Operation Yewtree, which was set up after abuse allegations against the late entertainer, Jimmy Savile, the court heard. Police got referrals from "all over the country" about Mr Travis, Ms Moore said. The court was told Mr Travis denies the assaults, and claims the alleged victims are motivated by greed for compensation and media attention. In one incident, alleged to have happened between 1976 and 1977, Mr Travis invited an 18-year-old into a "continuity suite" to choose a song, the jury was told. Mr Travis asked if she wanted to dance and pressed his groin against her, Ms Moore said. She told him to stop and he grabbed her and put the red light [signalling a live broadcast] on. He appeared to her to be getting angry," Ms Moore said, before he "put his hand up her skirt." Stood in dock Mr Travis, who hosted the Radio 1 Breakfast show from 1978 to 1980 and was a regular host of Top of the Pops in the 1970s and 80s, is accused of carrying out the offences between 1976 and 2008. The former DJ, of Mentmore, Buckinghamshire, stood in the dock as the charges, which relate to 11 female complainants, aged between 15 and 29 at the time, were read to the jury. They are: An indecent assault on a woman between 1 January 1976 and 31 December 1977 An indecent assault on a girl aged 15 on 17 June 1978 An indecent assault on a woman on 29 June 1978 An indecent assault on a woman between 1 January 1981 and 31 December 1983 An indecent assault on a woman between 1 January 1983 and 2 March 1984 An indecent assault on a woman between 1 January 1983 and 31 December 1984 An indecent assault on a woman between 1 November 1990 and 31 January 1991 Two counts of indecent assault on a woman between 1 November 1992 and 1 January 1993 Three counts of indecent assault on a woman between 1 January 2000 and 31 December 2003 An indecent assault on a woman between 1 January 2000 and 31 December 2003 A sexual assault on a woman between 1 June 2008 and 30 November 2008 Judge Anthony Leonard told the jury to try the case only on evidence heard during the trial. He warned the jury of four men and eight women that there should be "no sleuthing" on the internet and said they could be jailed for contempt of court if they broke the rules. The trial is expected to last up to six weeks.
