The number of victims who fell prey to Jimmy Savile could double, with current figures "a mere drop in the ocean", the child protection expert who helped expose the late entertainer as a paedophile has warned.
Mark Williams-Thomas, the criminologist who led the initial ITV Exposure documentary that revealed the Jimmy Savile abuse claims, said he could have targeted hundreds more victims.
"For anybody who works in this area the sheer scale is quite shocking. When you deal with sex offenders they are quite specific in their targeting", Mr Williams-Thomas said.
"What is different with Savile is that there's no specific target in terms of ages or sexes. He ranged from male to female, children to adults. It's truly shocking", he added.
Jimmy Savile could have been prosecuted for offences against at least three victims while he was alive, two separate reports said today.
The allegations began with the ITV documentary Exposure. Here are some of the key points as the case unfolded.
