Jimmy Savile
In a new recording Jimmy Savile appears to be taking advantage of a young girl

A damning new audio clip said to be of Jimmy Savile apparently preying on a young girl has surfaced online as Scotland Yard launches a fresh investigation into the entertainer's alleged child abuse.

The tape, believed to have been recorded in 1975, appears to be of an off-air conversation between Savile and a young woman.

In the chilling 90-second clip, exposed by Channel 4 News, the girl, who is clearly distressed, can be heard telling the Yorkshire-born DJ and presenter to "get off me" and "get off my backside".

Despite her protests, Savile continues and is heard repeatedly telling her to promise that he is "the only one" in her life.

The tape is the latest development in the scandal that has engulfed the former Top of the Pops host, who is accused of sexually assaulting more than 40 women during the 1960 and 70s.

It is understood that dozens of potential victims have continued to come forward daily to accuse the star of abusing them when they were children. The explosion of claims comes in the wake of an ITV documentary about Savile's alleged abuse.

The Metropolitan Police announced that would take the "national lead" in assessing the allegations.

The landmark investigation has put further pressure on the BBC, who Savile worked closely with throughout this career, to reveal whether some of the incidents took place on its premises.

The corporation, which initially reacted angrily to the allegations that it had turned a blind eye to the abuse, has now offered its full support to detectives.

A BBC spokesman said: "A number of serious and disturbing allegations have been made over the past few days about the sexual abuse of teenage girls by Jimmy Savile.

"Some of these allegations relate to activity on BBC premises in the 1960s and 70s.

"We are horrified by allegations that anything of this sort could have happened at the BBC - or have been carried out by anyone working for the BBC.

"We have asked the BBC investigations unit to make direct contact with all the police forces in receipt of allegations and offer to help them."

A statue of Savile has been removed from outside the Scotstoun Leisure Centre in Glasgow because it overlooked the children's swimming pool. It had stood on the site since 1993 in honour of Savile's charity work.
