DJ Dave Lee Travis has been charged with 11 counts of indecent assault and one of sexual assault against alleged victims aged between 15 and 29.

The 68-year-old, whose real name is David Patrick Griffin, is accused of committing the offences between 1977 and 2007, the Crown Prosecution Service said.

Chief Crown Prosecutor for CPS London, Alison Saunders, said: "We have carefully considered the evidence gathered by the Metropolitan Police Service as part of Operation Yewtree in relation to David Patrick Griffin, who was initially arrested on November 15 2012 over allegations of sexual offences.

"Having completed our review, we have concluded that there is sufficient evidence and it is in the public interest for Mr Griffin to be charged with 11 counts of indecent assault and one of sexual assault. These date from 1977 to 2007 and relate to nine complainants aged between 15 and 29 at the time of the alleged offending."

He is due to appear at Westminster Magistrates' Court on August 23.

The charges are:

- One offence of indecent assault relating to a woman, aged 18, in 1977.

- Two offences of indecent assault relating to a girl, aged 15, in 1977.

- One offence of indecent assault relating to a woman, aged 19, in 1978.

- One offence of indecent assault relating to a woman, aged between 26 and 28, on a date between 1981 and 1983.

- One offence of indecent assault relating to a woman, aged 18, in 1983.

- One offence of indecent assault relating to a woman, aged between 19 and 20, on a date in 1985.

- One offence of indecent assault relating to a woman, aged 22, in 1990.

- Three offences of indecent assault relating to a woman, aged between 26 and 29, from 2000 to 2003.

- One offence of sexual assault relating to a woman, aged 23, in 2007.

Prosecutors have decided that no further action should be taken in relation to seven separate allegations made against the DJ because there was not enough evidence.

Travis, from Bedfordshire, has consistently maintained his innocence since he was first arrested in November, and then re-arrested after further allegations emerged in March.

After his arrest over the additional allegations, he said: ''The last four months have been extraordinary. Allegations which I strongly deny have been put to me by the police and to which I have given full and complete answers. I have fully co-operated and my conscience is clear.''

He was charged as part of Operation Yewtree, the police investigation prompted by the Jimmy Savile abuse scandal, but the accusations against Travis have no connection to the disgraced television presenter.

Ms Saunders said: "The decision to prosecute has been taken in accordance with the Code for Crown Prosecutors and the Director of Public Prosecutions' interim guidelines on prosecuting cases of child sexual abuse. We have determined that there is sufficient evidence for a realistic prospect of conviction and that a prosecution is in the public interest.

"Mr Griffin will appear at Westminster Magistrates' Court on August 23 2013.

"We have also decided that no further action should be taken in relation to seven separate allegations against Mr Griffin as we determined that there was insufficient evidence for a realistic prospect of conviction.

"May I remind all concerned that Mr Griffin has a right to a fair trial. It is very important that nothing is said, or reported, which could prejudice that trial. For these reasons, it would be inappropriate for me to comment further."
