Jeffrey Epstein, the billionaire who allegedly supplied Britain's Prince Andrew with a 'sex slave', "may be the most dangerous sexual predator the [US] has ever seen", according to claims in a recently revealed lawyer's letter.
The revelation came as it emerged that the FBI allegedly possesses "secret documents" about the American magnate that could provide evidence for under-age "sex slave" accusations against him.
Epstein is accused of forcing a 17-year-old girl to have sex with Prince Andrew - a claim Buckingham Palace has denied.
The reported FBI documents are said to show that Epstein controlled under-age girls who could provide evidence about the claims.
In May last year, prosecutors surrendered 541 pages of correspondence with Epstein's lawyers leading up to a 2008 non-prosecution agreement, as part of an ongoing process by the alleged victims seeking access to around 15,000 pages of documentation.
'The Times' reported that a letter released by the court last year showed Brad Edwards, lawyer for alleged victim Virginia Roberts, telling the US attorney's office that Epstein "may be the most dangerous sexual predator that the country has ever seen".
Dated July 2008, the letter continued: "The evidence suggests that for at least four years he was sexually abusing as many as three to four girls a day.
"He is a sexual addict that focused all his free time on sexually abusing children, and he uses his extraordinary wealth and power to lure in poor, underprivileged little girls and then also uses his wealth to shield himself from prosecution and liability."
Earlier this week, it was reported that prosecutors believed that Epstein "pressurised witnesses" to hide the truth about claims that he procured underage girls for sex, according to 'The Telegraph'.
Lawyers for Ms Roberts - who claims that Epstein ordered her to have sex with Prince Andrew - have said that evidence against the billionaire was covered up after lobbying by his "political and social" connections.
Epstein pleaded guilty in 2008 to a single charge of soliciting prostitution and was handed an 18-month jail sentence.
He served 13 months in jail and was obliged to register as a sex offender.
Buckingham Palace has twice issued denials that Prince Andrew slept with Ms Roberts on three occasions between 1999 and 2002, in London, New York, and on a private Caribbean island.
Yesterday Sarah Ferguson praised her ex-husband as "the best man in the world". It also emerged yesterday that Ms Roberts, who also claims to have had underage sex with prominent criminal defence lawyer Alan Dershowitz, has filed a counter defamation lawsuit against him.
Former federal judge Paul Cassell and Florida plaintiffs attorney Bradley Edwards filed the lawsuit in a Florida circuit court, accusing Mr Dershowitz of initiating a public media assault on Ms Roberts's reputation and character, according to court documents.
In a filing in Florida federal court last week, Mr Cassell and Mr Edwards said their client Ms Roberts, who is identified as Jane Doe #3, was forced as a minor by financier Epstein to have sex with several people, including Dershowitz and Prince Andrew.
Prof Dershowitz filed a sworn statement in Florida federal court on Monday, denying he had sex with an underage girl on Epstein's private plane and island. In their lawsuit, Mr Cassell and Mr Edwards said Prof Dershowitz defamed them when he accused them of "deliberate misconduct and unethical behaviour warranting disbarment" during several interviews.
