The sex assault case against resigned IMF chief Dominique Strauss-Kahn could be close to collapse over reported doubts over the credibility of the maid who made the accusations against him.

Law enforcement officials say that since making her initial allegations on May 14, the 32-year-old has repeatedly lied, The New York Time reports.

Although forensic tests found evidence of a sexual encounter between the French Politician and the maid, prosecutors now do not believe much of what she has told them, the paper said.

Prosecutors have reportedly discovered inconsistencies with the Guinean immigrant's asylum application and possible links to criminal activities.

In earlier court hearings, prosecutors had appeared confident that they had a watertight case against DSK.

The woman alleges Strauss-Khan appeared naked from the bathroom of the Sofitel hotel suite, where she was working, before sexually assaulting her.

Strauss-Khan, who strenuously denies the charges, is currrently under house arrest in New York and is electronically tagged.

His very public arrest had the French media up in arms..

The 62 year old posted $6m (£3.7m) bond in May.

His lawyers are expected to ask for his bail conditions to be relaxed when he appears in court today.
