US LAWYER Gloria Allred claims the Duke of York is subjecting victims of Jeffrey Epstein to a "torture test" by not speaking out about "what he knows".

Allred, who represents some of the victims, said Andrew is "avoiding and evading" US law authorities by not providing a statement.

She told Good Morning Britain: "The question is, Prince Andrew when is he going to tell what he knows?

"He needs to do that. He needs to do it without delay. It is so traumatising and difficult for the victims not to know the truth.

"And this kind of torture test that Prince Andrew is subjecting the victims to, like will he or won't he give a statement, if he will, when?

"More excuses, more delays, it really is painful for many of the victims. It's just not fair."

A lawyer for some of the alleged victims of Jeffrey Epstein has called on the Duke of York to come forward and speak to US prosecutors about his friendship with the financier.

Spencer Coogan said his clients were "relieved" that Ghislaine Maxwell, who had introduced her friend Andrew to her former partner, had finally been arrested on charges of facilitating Epstein's sexual exploitation of underage girls.

He told the BBC Radio 4 Today programme: "I certainly think Prince Andrew has a story to tell. On behalf of the victims be have continuously asked him to step forward, step up, be a man and tell us what he knows.

"He has been hiding behind not only the royal family but his attorneys.

"Regardless of his position we, on behalf of the victims, hope that he will step forward and speak up about what he witnessed, at the very least when he was visiting the (Epstein) mansion in New York, when he visited the home in Palm Beach and when we know he was down visiting the Virgin Islands' mansion."

Boris Johnson has declined to say how the UK Government would respond if the US authorities made an approach to interview the Duke of York.

Asked about the response during an interview on LBC, the Prime Minister said: "No such approach has been made and otherwise it really is a matter for the royal family."

Prince Andrew faces accusations from Virginia Giuffre, who has claimed she was forced to have sex with him at Maxwell’s home in London when she was 17. Her claims have been repeatedly denied by the prince.

Maxwell, the former girlfriend of Epstein, was arrested yesterday and charged with playing a role in his abuse of minor girls. The court filing states she helped “Epstein to recruit, groom and ultimately abuse” girls under the age of 18.

Maxwell has been absent from the public eye since Epstein was arrested last June on charges of sex trafficking.

Her lawyers have fought away allegations that she was involved in Epstein's abuse of dozens of young girls for years by denying them in civil lawsuits.

She has made no public comment about the scandal since Epstein was found dead in his jail cell last summer.
