A US judge released Dominique Strauss-Kahn on his "own recognizance" Friday, but prosecutors who consented to the easing of bail restrictions did not agree to dismiss the sexual assault case against the former IMF chief. The French politician was in a New York courtroom for a brief but extraordinary hearing that came in the wake of reports that prosecutors had grave doubts about the credibility Strauss-Kahn's accuser, and while sources suggested to US media that the case had serious problems, the judge stressed that the "case is not over."
