Stunned officers chipped away plaster at a ­record shop wall and unveiled a hidden list of names thought to belong to young victims of Jimmy Savile.

The vile register, which contained the names, ages and a disgusting ratings system seemingly used to mark their sexual performance, was scrawled on a secret wall buried behind layers of wallpaper and plaster.

A source revealed: “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.”

The list of girls and young women is thought to identify ­hundreds of potential new victims abused at the hands of the BBC DJ and it raised fears Savile was at the centre of a celebrity paedophile ring.

Police believe the major breakthrough could lead to further arrests – including other well-known celebrities.

The wall also appeared to contain the names of girls the sick group hoped to target in the future.

Officers who raided the shop in ­Greater Manchester after a tip-off will now try to trace the alleged victims.

A source said the raid had provided the clearest evidence yet to show Savile was part of a larger group of monsters.

The source said: “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.”

As the specialist officers ripped away the layers from the wall, the names of up to 200 new ­people they believe he and accomplices attacked or planned to
attack during the 1980s and 1990s were ­gradually revealed.

At least one other well-known BBC figure and several celebrities are now being linked to the probe. Suspects face being quizzed in the coming weeks.

The source added: “Police think there might be hundreds of new female victims that needed to be spoken to as a result of the record shop raid.

Earlier this year it was suggested there were around 450 victims of Savile’s depraved actions.

“This looks like an under-estimation. If the evidence on the wall is anything to go by, we could be talking in the region of 650 victims in all. It’s shocking.”

Criminologist Professor David Wilson from Birmingham City University said the register was a way for the predators to boast about their conquests.

He said: “In the age before the internet made it possible for paedophiles to ­communicate with each other and write about who they could abuse and the form that abuse may take, they found other methods.

Paedophiles are constantly evolving ways of communicating.

“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.

“They also recognise this could lead to arrest, so they had to be careful about their sexual preferences.

“At the time this was said to have taken place paedophiles used contact magazines and groups of associates to get in touch with each other.

We are beginning to see how widespread Savile’s abuse was.

“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.

Now they download songs on the internet.”

Police carried out the raid a few weeks ago. The findings potentially raise the depravity of disgraced Savile – who died at 84 in October 2011 – to new levels.

A joint police and NSPCC report published in January declared that with at least 450 victims, he was one of Britain’s most ­prolific sex offenders.

Commander Peter Spindler said Savile “groomed the nation” as he raised millions for charity while using his status as a platform for abuse.

Leeds-born Savile had links with ­Greater Manchester stretching back to the 1950s when he managed a ballroom in the city.

His first known attack took place in ­Manchester in 1955. Investigators who revealed the scale of his abuse said he used his appeal to target the vulnerable.

In 1964, Savile’s name was mentioned to police investigating allegations that men were exploiting girls from Duncroft ­Approved School in Surrey.

Police arrested two men in London and a ledger showed Savile was a regular ­visitor there. Following his death, 28 police forces recorded 214 crimes ­committed by the presenter, including 34 rape claims. The latest allegation against him was from 2009 when he was aged 82.

The report said he targeted children as young as eight and sexually attacked at least 23 of his victims on BBC premises.

In 1972 during a break in filming, Savile groped a 12-year-old boy and felt the breasts of the youngster’s two friends.

Investigators also found he carried out abuse in at least 14 hospitals between 1955 and 2009, including Great Ormond Street and one hospice.

Savile was stripped of his knighthood when dozens of women came forward to say he attacked them during his 54-year campaign of abuse.

Officers launched Operation Yewtree to probe the claims and there are now three strands to the investigation. One concerns Savile’s crimes ­exclusively, while another relates to allegations against Savile and others.

The third concentrates on ­accusations unconnected to Savile but which emerged following publicity.

A host of soap stars, DJs and TV ­presenters have been arrested during nationwide probes into historical sex offences in cases not connected to Savile.

BBC presenter Stuart Hall had his prison sentence for a series of assaults on girls doubled to 30 months on Friday.

Three Appeal Court judges ruled his original 15-month term was “inadequate”. The former It’s A Knockout host, 83, ­admitted sexually assaulting 13 girls aged nine to 17 over nearly 20 years.

Coronation Street star Bill Roache is one of the best-known actors to be held over allegations in the aftermath of the Savile scandal. He was charged in May with raping a ­teenage girl in 1967.

Roache has been bailed until his next court appearance on September 2 when he will enter formal pleas.

The actor, who has played Ken Barlow in the ITV1 soap since its launch, also faces charges of five indecent assaults­ ­involving four girls aged between 11 or 12 and 16. He denies all the claims.

His fellow Corrie star Michael Le Vell, who plays mechanic Kevin Webster, has been taken off air after being charged with 19 offences against a child, including rape, indecent assault and sexual activity.

Police have been inundated with calls following coverage of Savile’s depraved legacy.

It is claimed more of those ­allegedly abused are now finding the courage to come forward because the police are taking a new approach – giving potential victims hope their cases will be treated seriously.

Dozen of other arrests so far include Gary Glitter and comedian Freddie Starr.

Comic Jimmy Tarbuck was ­arrested at his home in South West London in May in ­connection with a historic child sex abuse claim.

And PR guru Max ­Clifford has been charged with 11 indecent assaults allegedly committed ­between 1966 and 1985.

The 70-year-old has vowed to clear his name. All those who have been ­arrested have vehemently ­denied any wrongdoing.
