NEW YORK (

TheStreet

) -- A New York judge dropped sexual assault charges on Tuesday against former International Monetary Fund Chief Dominique Strauss-Kahn after prosecutors determined there wasn't enough evidence to pursue the case.

Earlier Tuesday, the judge rejected the accuser's request for a special prosecutor to oversee her case, a day after the

Manhattan district attorney's office said that it intended to drop the case that began in May.

Former International Monetary Fund leader Dominique Strauss-Kahn

A housekeeper at the Manhattan hotel in which Strauss-Kahn stayed claimed that he sexually assaulted her on May 14. The former IMF head attempted to leave the United States the next day on an Air France flight, but was arrested by authorities before he could depart.

Strauss-Kahn was held at Rikers Island in New York before a judge allowed him to post bail.

Before the contentious incident, Strauss-Kahn was favored by many to oppose French President Nicolas Sarkozy. But the events of the past three months may have all but eliminated a possible run at the post.

It was expected that Strauss-Kahn's passport would be returned to him immediately so that he could return to his home in France.
