( CNN ) A woman claims in a federal court filing this week that she was forced to have sex with several men -- including Britain 's Prince Andrew -- while a teenager , an allegation the Duke of York 's camp firmly denies . A royal family spokesman in London labeled the accusation against Prince Andrew `` categorically untrue . '' The woman made the allegation in a civil motion filed Tuesday in U.S. District Court in southern Florida , joined by another unnamed woman . Both are seeking to join two other women who are arguing in federal court for the U.S. government to take a fresh look at its case involving self-made billionaire Jeffrey Epstein , who pleaded guilty some years ago in Florida to a state charge of prostitution solicitation . The investment banker agreed to a state plea deal in 2007 and began serving an 18-month sentence in 2008 , said The New York Times . According to The Times and the Washington Post , Epstein was the subject of a federal investigation but a deal allowed him to plead guilty to the lesser state charge and avoid a potential federal case . The four women allege their rights under the Crime Victims ' Rights Act were violated because the U.S. `` government secretly negotiated a non-prosecution agreement '' with Epstein . According to the new court filing , the women contend they were not properly informed by the government about the ongoing status of a possible federal prosecution . It also claims Epstein used `` powerful political and social connections to secure a favorable plea deal . '' Tuesday 's filing claims the two new alleged victims were sexually abused and exploited by Epstein , one beginning when she was 15 and the other when she was 16 . One of them , referred to as Jane Doe # 3 in the document , claims that an accomplice who Epstein `` used to procure under-aged girls for sexual activities '' approached her in 1999 . That alleged female accomplice allegedly `` regularly participated in Epstein 's sexual exploitation of minors '' and assisted Epstein as he made Jane Doe # 3 into a `` sex slave '' from 1999 to 2002 , the filing says . The court filing makes claims against others allegedly involved `` in Epstein 's sexual abuse ring , '' saying , `` Epstein also sexually trafficked the then-minor Jane Doe , making her available for sex to politically-connected and financially-powerful people . '' Prince Andrew was one of those named , with the filing claiming that Jane Doe # 3 `` was forced to have sexual relations with him when she was a minor '' in London , New York and on Epstein 's private island in the U.S. Virgin Islands . A palace spokesman , who is not named per custom , pointed out Friday that Prince Andrew , the Duke of York , is not a direct party to the `` ongoing civil proceedings in the United States . '' Andrew is a son of Queen Elizabeth II and a brother of Prince Charles , the next in line for the British throne . `` As such we would not comment on the detail , '' the palace spokesman said . `` However , for the avoidance of doubt , any suggestion of impropriety with underage minors is categorically untrue . '' Also accused in the court filing this week of sexually abusing Jane Doe # 3 was noted law professor Alan Dershowitz . `` Epstein required Jane Doe # 3 to have sexual relations with Dershowitz on numerous occasions while she was a minor , not only in Florida but also on private planes , in New York , New Mexico , and the U.S. Virgin Islands , '' the filing states . Dershowitz issued an adamant denial , saying the case `` is all about money . '' `` The entire story is completely made up , '' Dershowitz said in the statement . `` I have challenged her lawyers for her to repeat these statements in public so that I can sue them for defamation and I have challenged her to file criminal charges against me , because the filing of false criminal charges , which this one is , is a serious crime , '' he added . A lawyer for Epstein also dismissed the allegations . `` These are stale , rehashed allegations that lawyers are now attempting to repackage and spice up by adding the names of prominent people , '' said Epstein 's attorney , Jack Goldberger . `` The allegations , which are outlandish on their face and discredited by the evidence , were made in a civil case in which Mr. Epstein is not a party . '' An attorney for the alleged victims , Brad Edwards , said that he was `` not able to comment beyond our pleadings at this point nor respond to any denials or threats by anyone . '' Through Edwards ' office , Jane Doe # 3 issued a statement saying she is `` looking forward to vindicating my rights as an innocent victim and pursuing all available recourse . It appears that I am now being unjustly victimized again . '' CNN 's Phil Gast , Mayra Cuevas and Chandler Friedman contributed to this report .
