US prosecutors will drop all sexual assault charges against former IMF chief Dominique Strauss-Kahn as the case is not sustainable due to doubts over the accuser's credibility, according to an investigator.
"Prosecutors will agree to drop the charges against Dominique Strauss-Kahn -- either on his next court date in two weeks or even sooner," New York Post quoted a top investigator in the case as saying.
He called the eventual dismissal "a certainty."
"We all know this case is not sustainable," the source told the newspaper.
"Her credibility is so bad now, we know we cannot sustain a case with her," the source said, referring to the Guinean hotel maid who accused Strauss-Kahn of trying to rape her in his suite at the Sofitel hotel in Manhattan.
The shocking charges got the international banker bounced as head of the IMF and also derailed, at least for now, his bid to become president of France.
"She is not to be believed in anything that comes out of her mouth -- which is a shame, because now we may never know what happened in that hotel room," said the source.
"Did [Strauss-Kahn] use force? Was there actually a crime? I don't think we'll ever know."
The 32-year-old hotel maid is under intense scrutiny after New York prosecutors told a court on Friday that they had found holes in her story which may seriously damage her credibility as a witness.
Strauss-Kahn, 62, was accused of forcing the maid to perform oral sex.
He was bundled out of a Paris-bound flight and taken into custody. He was charged with sexual abuse, unlawful imprisonment, forcible touching and harassment.
