PRINCE Andrew had an orgy with nine girls on Jeffrey Epstein's 'paedo' island, the billionaire's 'sex slave' has claimed.

Virginia Roberts was 18 when she had her third alleged sexual encounter with the royal on Little St James island, US Virgin Island.

It marks the first time Ms Roberts - who has since changed her surname to Guiffre - has shared an insight on the alarming claims involving the Duke of York.

Andrew has always denied any wrongdoing during his friendship with the disgraced financier, which began after the two met in 1999.

He also claims never to have "seen, witnessed, or suspected" the behaviour that led to Epstein's 2008 conviction for soliciting an underage girl for prostitution, for which he served 13 months in custody.

But Channel 4's Dispatches programme revisited evidence Ms Roberts gave a Florida court in 2015.

She said at the time: "Epstein, Andy, approximately eight other young girls and I had sex together.

"The other girls all seemed and appeared to be under the age of 18 and didn’t really speak English.

"Epstein laughed about the fact they couldn’t really communicate, saying that they are the ‘easiest’ girls to get along with.”

Epstein, who bought the island two decades ago, was found dead in his cell in August, weeks after being charged with child-trafficking offences.

The alleged sex slave claims she had sex with the Prince aged 17 - which he strongly denies.

He was once pictured with his arm around her when she was 17 at a party thrown by billionaire Epstein, which supporters of the royal have suggested is fake.

Prince Andrew previously released a statement condemning his former pal, saying: "It is apparent to me since the suicide of Mr Epstein that there has been an immense amount of media speculation about so much in his life.

"This is particularly the case in relation to my former association or friendship with Mr Epstein. Therefore I am eager to clarify the facts to avoid further speculation.

"I met Mr Epstein in 1999. During the time I knew him, I saw him infrequently and probably no more than only once or twice a year. I have stayed in a number of his residences.

"At no stage during the limited time I spent with him did I see, witness or suspect any behaviour of the sort that subsequently led to his arrest and conviction."

The Duke was last pictured with Epstein in New York in 2010 after the hedge fund manager had been released from prison and was a registered sex offender.

Workers claimed Epstein's mansion on his island had a music room, "reinforced lock bar across the outside... as if it were to lock people in".

Chicago-based contractor James Both shared his professional thoughts on the building's door with Business Insider.

"It's styled like what you might see on a castle, with what appears to be a reinforcing lock bar across the face," he said.

"What makes it peculiar is that if you wanted to keep people out, the bar would be placed inside the building, [but the] locking bar appears to be placed on the outside ... as if it were intended to lock people in."
