A reformed jewel thief has reportedly claimed that Jeffrey Epstein and Ghislaine Maxwell filmed powerful people having sex with underage girls.

The man, using a pseudonym, claims the one-time power couple made him watch some to prove how they “owned” people.

William Steel, an ex criminal turned writer, says he was shown footage of two high-profile US politicians having sex with minors.

Steel said that Maxwell, who was arrested last week in connection with trafficking young girls, was a 'nymphomaniac'.

Maxwell denies all wrongdoing.

Speaking to The Sun Mr Steel said: "I was forced to watch their videos because they were trying to impress me.

"They wanted to convince me of their power and who they held in their grip.

"They boasted about ‘owning’ powerful people."

In 2018, Steel wrote a memoir called Sex And The Serial Killer — about his relationship with multi-millionaire suspected serial killer Robert Durst.

He now says that he had originally included some of what he claims to have witnessed at Epstein's Palm Beach Mansion - but those pages had to be redacted for legal reasons and were never published.

He has pledged to give all his information to the authorities and testify in court.

Mr Steel says he had a sexual relationship with Maxwell but minors were never involved despite him frequently seeing underage girls coming and going from the oceanfront mansion on El Brillo Way, Palm Beach.

Steel is now planning to write a book about his experiences with the pair.

He told the newspaper that he 'wants to right the wrongs' he's caused and 'to give something back'.

Maxwell was arrested in a hideout in Bradford, New Hampshire, last week and charged with conspiring with Epstein to traffic young girls for sex.

She is currently being held at the Metropolitan Detention Center in Brooklyn ahead of a hearing on Tuesday.

That hearing will decide whether she will be granted bail.

On Friday Maxwell forcefully denied charges she lured underage girls so he could sexually abuse them, and said she deserves bail.

The one-time socialite filed her request in the US District Court in Manhattan eight days after her arrest.

The 58-year-old Maxwell "vigorously denies the charges, intends to fight them, and is entitled to the presumption of innocence," the filing says.

Prosecutors have called Maxwell an "extreme risk of flight" who should remain detained until trial.

The arrest of Maxwell came nearly one year after Epstein pleaded not guilty to charges he sexually abused women and girls in Manhattan and Florida.

Epstein died last August at the age of 66 by hanging himself in jail.

He had before his arrest socialized over the years with many prominent people including Prince Andrew, President Donald Trump and former President Bill Clinton.

Prosecutors accused Maxwell of recruiting girls as young as 14 for Epstein from 1994 to 1997.

Maxwell faces six criminal charges, including four related to transporting minors for illegal sexual acts, and two for perjury in depositions about her role in Epstein's abuses.
