Former Radio 1 DJ Dave Lee Travis has been charged with 11 counts of indecent assault and one count of sexual assault against nine woman aged between 15 and 29.

Travis, 68, was initially arrested in November under Operation Yewtree, the inquiry into sex offences set up in the wake of the Jimmy Savile scandal. He was rearrested when he answered bail in March.

The charges levelled against Travis relate to incidents which took place between 1977 and 2007. The Crown Prosecution Service said seven separate allegations should be dropped due to insufficient evidence.

Travis, real name David Patrick Griffin, will appear at Westminster Magistrates' Court on 23 August 2013 to face the charges. He has "categorically" denied all the allegations against him.

Fourteen people have been arrested since the opening of Yewtree, which was set up by Scotland Yard to investigate alleged sexual offences by Savile and others.

Travis, PR guru Max Clifford and former BBC chauffeur David Smith are the only ones to have been charged with sex offences.

Other high profile names arrested under the operation include Freddie Starr, Jim Davidson and Gary Glitter.

An 80-year-old man arrested this week over accusations of sexual offences has been released on bail.
