New York (CNN) -- A New York judge dismissed sexual assault charges against former International Monetary Fund chief Dominique Strauss-Kahn at the prosecutor's request Tuesday. A grand jury indicted Strauss-Kahn in May over allegations he sexually assaulted hotel housekeeper Nafissatou Diallo in his New York hotel suite. But in July, prosecutors began to back off the case, asking Judge Michael Obus to release Strauss-Kahn from house arrest after information surfaced that they said called Diallo's credibility into question. On Monday, prosecutors asked Obus to dismiss the charges entirely, while Diallo's attorney filed a motion asking that Manhattan District Attorney Cyrus Vance be disqualified from the case and that a special prosecutor be appointed.

In a statement, @placeholder -- who has always denied the charges --  thanked his attorneys and Obus for his decision.
He rejected explanations by @placeholder's attorneys that any sexual encounter that may have occurred was consensual, questioning how he could persuade a woman he had never met before to have sex during a nine-minute encounter.
