A lawyer for the hotel maid who accused former International Monetary Fund director Dominique Strauss-Kahn of sexual assault says New York prosecutors are expected to dismiss the case.

Nafissatou Diallo's lawyer says the Manhattan District Attorney's office summoned Diallo to a meeting Monday to inform her of a decision to drop the charges against Strauss-Kahn, a former French finance minister who stepped down as IMF head after police arrested and jailed him.

The attorney's office has not confirmed such a decision.

New York media say prosecutors will formally dismiss the case at a Tuesday hearing because of revelations about the accuser that could undermine her credibility in front of a jury.

The case faltered in late June when prosecutors revealed inconsistencies in Diallo's account of what happened May 14 in the luxury Sofitel hotel, where she was assigned to clean the suite where Strauss-Kahn was staying.

She accused the then-IMF chief of sexually assaulting her after she entered his room. His lawyers have suggested that any sexual encounter was consensual.

New York prosecutors also later disclosed that Diallo had fabricated a story about being gang-raped in her native Guinea for her U.S. asylum application.

Prior to the incident, Strauss-Kahn, who was released on bail, was a leading Socialist contender to challenge French President Nicolas Sarkozy in an election next year. His arrest has significantly eroded his support among the French electorate.
