Accuser credibility questions shake IMF sex case

Prosecutors have serious questions about the credibility of a hotel housekeeper who has accused former International Monetary Fund leader Dominique Strauss-Kahn of sexual assault, and he is expected to have his strict bail conditions reduced today, according to people familiar with the case.

Investigators have come to believe that the woman lied about some of her activities in the hours around the alleged attack and about her own background, a law enforcement official told The Associated Press on Thursday. The official is familiar with the case but spoke on condition of anonymity to discuss matters not yet made public in court.

Prosecutors think she lied about details on her application for asylum in the U.S., including saying she had been raped in her native Guinea, the official told the AP.

"She actually recounted the entire story to prosecutors and later said it was false," the official said.

Prosecutors haven't necessarily reached a new conclusion about the allegations against Strauss-Kahn and have not decided whether to downgrade the charges, the official said.
