Police have found a list of hidden names thought to belong to paedophile DJ Jimmy Savile's young victims, scrawled on a secret wall in a Manchester record shop.

The names and sexual details of hundreds of young girls have been discovered, hidden under a layer of plaster in a room above a record shop.

The register contained names, ages and a ratings system apparently used to mark their sexual performance. It was scratched on a secret wall hidden behind layers of plaster and wallpaper.

"The wall looked like something straight out of a horror movie. There were lists and lists of names of the victims - it's a shocking discovery," a source told the Mirror.

"Savile appeared to be using the room above the record store as some kind of secret HQ to plan his vile acts.

"There appears to be some suggestion that he was not acting alone, either.

"There were others who appear to be involved, several others, some of whom are household names."

Police now want to identify the hundreds of potential new victims, to uncover evidence that Savile was part of a celebrity paedophile ring.

The major breakthrough could lead to further arrests of UK celebrities.

As police officers ripped away the plaster, the names of up to 200 people whom Savile and his accomplices attacked or planned to, was revealed.

At least one other famous BBC personality and several celebrities are linked to the new investigation, and suspects could be quizzed in the near future.

Savile was thought to have preyed on around 450 victims, but this new revelation could push the number up to 650.

Criminologist Professor David Wilson of Birmingham City University said the register was a way for the predators to document, record and boast about their sexual conquests.

He said: ""By putting it on a wall they are making it public, but by hiding it, it is private. The public nature is because they are proud of it. It is a boasting system.

"It is a form of saying, 'this is what I've done. I've done more than you'.

"It's about them displaying their own sexual success in being able to abuse these children.

"The significance of it having been found in a record shop is that at the time this was where all the young people went to buy their records and hang out."
