Prosecutors and attorneys for French politician Dominique Strauss-Kahn agreed Tuesday to postpone next week's court hearing in his sex-assault case for three weeks.

In a terse, one-line statement, a spokesman for Manhattan District Attorney Cyrus Vance Jr. said next Monday's court date will be pushed back to Aug. 23.

"The investigation into this pending criminal case is continuing," spokeswoman Erin Duggan said.

Defense attorneys for Strauss-Kahn, 62, who faces charges that he sexually assaulted a maid at the Sofitel hotel in Manhattan on May 14, seemed certain Vance would drop the case.

"We are confident that when the investigation is completed, Mr. Vance will move to dismiss all charges against Dominique Strauss-Kahn," attorney Benjamin Brafman said.

Yesterday's adjournment was the second for the case. A July 18 appearance before Manhattan State Supreme Court Judge Michael Obus was put off until next Monday so prosecutors could continue to investigate after questions were raised by prosecutors about the credibility of Strauss-Kahn's accuser, Nafissatou Diallo, who herself is suspected of lying to investigators and to the grand jury.

The adjournment also comes just a day after Diallo, 32, who is from Guinea, talked openly about the incident in interviews with Newsweek and ABC News.

A law enforcement official familiar with the investigation who didn't want to be named said Diallo's decision to give the interviews didn't come as a surprise to investigators, who were nonetheless displeased.

Some remarks Diallo made in the interviews appeared to differ from her earlier statements. But it was unclear if Diallo's interview remarks differed from what she told the grand jury that indicted Strauss-Kahn.
