Prosecutors Friday released former IMF Director Dominique Strauss-Kahn, after serious questions were raised about the credibility of the woman who accused him of sexual assault.

Investigators in the Manhattan District Attorney's office have 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.
