“She recalled being led into a room that was filled with candles on the lowest level of the hospital, somewhere that was not regularly used by staff. Several adults were there, including Jimmy Savile who, like the others, was wearing a robe and a mask.

“She recognised him because of his distinctive voice and the fact that his blond hair was protruding from the side of the mask. He was not the leader but he was seen as important because of his fame.

“She was molested, raped and beaten and heard words that sounded like ‘Ave Satanas’, a Latin­ised version of ‘Hail Satan’, being chanted. There was no mention of any other child being there and she cannot remember how long the attack lasted but she was left extremely frightened and shaken.”

Savile was a volunteer porter and fundraiser at the hospital between 1965 and 1988 and had his own quarters there.
