Prosecutors will agree to drop the charges against former International Monetary Fund chief Dominique Strauss-Kahn -- either on his next court date in two weeks or even sooner, the New York Post reported Tuesday citing a top investigator in the sexual assault case who called the eventual dismissal "a certainty."

"We all know this case is not sustainable," the source told The Post.

"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 plush Manhattan hotel suite -- shocking charges that 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, who is at the center of the investigation and would speak only on the condition of anonymity. "Did [Strauss-Kahn] use force? Was there actually a crime? I don't think we'll ever know."
