Jimmy Savile abused victims at BBC properties in Glasgow and raped a girl from Scotland, a new report has revealed.

The dossier from retired judge Dame Janet Smith says Savile and Stuart Hall were able to operate with impunity at the BBC.

It claims the corporation missed five opportunities to stop them and says Savile committed attacks at "virtually every one of the BBC's premises at which he worked", including studios in Glasgow, Manchester, Leeds and London.

Savile assaulted one 12-year-old girl when she travelled from Scotland to London to watch Top of the Pops in December 1973.

After watching the show the girl and a ten-year-old boy were taken backstage and raped by Savile, who was wearing a Womble costume. He later told them it was their "little secret".

The girl contacted police in April 2014 after seeing an advert asking Savile's victims to come forward in a newspaper.

BBC staff missed a series of opportunities dating back to the late 1960s to stop Savile, who died in October 2011 aged 84 never having been brought to justice for his crimes and is now believed to be one of Britain's most prolific sex offenders.

The 1448-page report published on Thursday said the "most serious incidents of rape and attempted rape" happened at properties owned by Savile. The presenter's remote three-bedroom home in Glen Coe was sold for £212,000 in 2013.

Dame Smith concluded: "In summary, my conclusion is that certain junior and middle-ranking individuals were aware of Savile's inappropriate sexual conduct in connection with his work for the BBC.

"However, I have found no evidence that the BBC, as a corporate body, was aware of Savile's inappropriate sexual conduct in connection with his work for the BBC."

BBC staff failed to report disgraced It's a Knockout presenter Stuart Hall's "inappropriate sexual conduct" partly because he was seen as an "untouchable" celebrity, the report added.

Investigators said he had 21 female victims at the BBC between 1967 and 1991 - the youngest aged ten - but no complaints were made to senior management.
