The chambermaid who accused former IMF Director Dominique Strauss-Kahn of sexual assault admitted that she lied to a grand jury about the events surrounding the alleged attack, according to a letter sent from prosecutors to Strauss-Kahn's defense team.

Forensic tests found evidence of a sexual encounter between Strauss-Kahn, a French politician, and the woman, but prosecutors now do not believe much of what the accuser has told them about the circumstance or about herself, The New York Times reported.

The 32-year-old woman from Guinea accused Strauss-Kahn of chasing her through a luxury suite in May, attempting to pull down her pantyhose, and forcing her to perform oral sex on May 14, since then, a law enforcement official said, the accuser has repeatedly lied.

In a letter dated June 30, prosecutors say she admitted she cleaned another room following the encounter with the French politician and then returned to Strauss-Kahn's room and cleaned, too, contradicting what she told a grand jury, CBS News reported.

The latest revelation in the case has damaged the maid's credibility and further undermined the prosecution of Strauss-Kahn. And as a result, a New York judge released Strauss-Kahn from house arrest, though charges against him remain.

Kenneth Thompson, an attorney for Strauss-Kahn's accuser, said, The only defense Dominique Strauss-Kahn has is that this sexual encounter was consensual. That is a lie.

[She] made some mistakes but that doesn't mean she is not a rape victim, Thompson added. He also says she was mistreated by prosecutors questioning her regarding the case. Prosecutors allegedly screamed and yelled at the woman to Get out! Get out of here! Leave, Thompson said 

Investigators in the Manhattan District Attorney's Office discovered significant inconsistencies with the account of the chambermaid who claimed Strauss-Kahn sexually assaulted her in a luxury hotel room in May, sources said Thursday.

Revelations the accuser allegedly considered financial gain and engaged in relationships categorized as questionable with a drug dealer prompted Manhattan prosecutors to inform his lawyers and submit to a bail modification hearing Friday, court sources said.

The chambermaid who accused former IMF-chief Dominique Strauss-Kahn of sexually assaulting her in a luxury Manhattan hotel admitted to fabricating an account of being gang raped by soldiers in Guinea, where she hails from, calling into to question her credibility as a suspect in the case.

During a grand jury testimony, the accused lied about the case, saying she was fearful after the attack, when evidence from prosecutors contend she cleaned two suites including the scene of the alleged crime, court papers said.
