A COP who exposed paedophile BBC star Jimmy Savile said the broadcaster MUST name the presenter who allegedly paid a teen for sexual pics.

Met Police investigators have been called in by the BBC after it suspended the star, who is accused of giving the youngster more than £35,000 for sordid snaps.

Former Surrey Police detective Mark Williams-Thomas, who exposed Savile as a paedo, said that the public need to know who the presenter is.

He told the Mirror: “It’s the same failed process as Savile, yet again.

“The BBC has already had a month to look into this – they should have concluded their investigation by now and named the individual in question.

“It’s all about openness and transparency, but the BBC has got a track record of carrying out fatally flawed investigations.”

The star accused of paying a teenager for sex images made two panicked calls to them after The Sun revealed the bombshell claims.

The presenter, who was suspended today, allegedly rang last week asking: “What have you done?”

It is claimed he also asked the youngster to ring their mum to get her to “stop the investigation”.

The Government demanded answers from BBC chief Tim Davie as the Met Police were contacted as part of the investigation.

It came as Beeb sources admitted: “The BBC has started to receive calls from the public about the behaviour of the person at the centre of the investigation.”

The family of the teen, now 20, were upset with the wording of the BBC’s statement on the star’s suspension.

Latest on BBC sex probe:

It said “new allegations” came to light on Thursday.

The family say no one from the corporation rang them for a proper interview after the initial complaint.

On Saturday night the family handed a dossier of evidence to the broadcaster’s lead investigator, ex-cop Jeff Brown.

The claims include one that the presenter has given the youngster over £35,000 since they were 17.

In an interview with The Sun on Sunday, the mother said the family complained in May but became frustrated that the star was still on air a month later.

Earlier the mum told how the teenager used the man’s alleged funds to feed a drug addiction.

She said they had gone from a “happy-go-lucky youngster to a ghost-like crack addict” in just three years.

Several BBC stars including ­Jeremy Vine, Nicky Campbell, Gary Lineker and Rylan Clark have publicly said it is not them.

Earlier Culture Secretary Ms Frazer said Mr Davie had reassured her the broadcaster was “investigating swiftly and sensitively”.

She said: “Given the nature of the allegations it is important that the BBC is now given the space to conduct its investigation, establish the facts and take appropriate action. I will be kept updated.”

It is understood that no timeline has been put on the probe. Caroline Dinenage, the Tory chairwoman of the Culture Select Committee, has also spoken with Mr Davie.

Politicians let rip at the lack of answers from the BBC after it failed to publicly address key questions surrounding the probe.

Former Culture Minister Damian Collins said: “I think the concern will be that this was raised by the family in May this year, but what happened when the complaint was initially raised?

“Why didn’t they do something sooner, I think is a fair challenge to the BBC.”
