Arraignment for Dominique Strauss-Kahn, leader of the International Monetary Fund, was delayed late Sunday evening due to “scientific and forensic examinations” requested by the government, his lawyer said Sunday evening.

William Taylor, speaking to the press outside the Manhattan Criminal Court in Lower Manhattan after 10 p.m. Sunday, said his client “willingly consented” to the requested examination. Taylor added that Strauss-Kahn is “tired, but he’s fine.”

Strauss-Kahn, 62, one of the strongest contenders for French presidency, allegedly sexually assaulted a maid at the Sofitel Hotel in mid-town Manhattan on Saturday afternoon. He was taken off an Air France flight at John F. Kennedy International Airport later in the day Saturday by the Port Authority police, just minutes before the plane was supposed to take off for Paris, according to NYPD Deputy Commissioner Paul Browne.

Strauss-Kahn is charged with a criminal sex act, attempted rape and unlawful imprisonment. “He intends to vigorously defend these charges, and he denies any wrongdoing,” Taylor said.

The arraignment is expected to take place on Monday morning.
