The grandchild of Sir Jimmy Savile's sister has accused the late British entertainer of abusing her as a child.

Caroline Robinson, Savile's great niece, claims she was molested by the star when she was 12 years old and again three years later.

Robinson tells Britain's Daily Mail, "When I was younger I had flashbacks. They invaded my dreams. I re-lived everything that happened to me in slow motion. I'd wake up sweating. I saw the whole scene as if I was a detached observer looking down on it, and the worst thing is I couldn't make it stop. I'd shout but the words wouldn't come out... What Jimmy did to me was terrible."

The 49 year old's account comes just a day after British police launched a criminal inquiry into abuse allegations against Savile amid reports he molested more than 200 children over a period of 40 years.

Robinson adds, "I kept it close for so long. But when I started reading about all the other girls he had abused I thought: 'This sounds just like what happened to me.' I think it should be aired: Jimmy had done this to one of his own family."

Savile died last year (11).
