Strauss-Kahn, a veteran French politician, was picked up out of a police lineup by the chambermaid last night, who has accused him of molesting her, according to media reports.
The French financial wizard's arraignment was put off for a day after he agreed to forensic testing requested by the police as his attorney Benjamin Brafman vowed that his client proposed to fight charges of sexual assault.
Strauss-Kahn, a likely candidate for 2012 presidential race in France, has been charged with attempted rape, sexual assault and unlawful imprisonment.
62-year-old IMF chief has denied the charges against him. Police allege that Strauss-Kahn sexually assaulted the 32-year-old woman Saturday at the Sofitel hotel in Manhattan, then quickly headed off to New York airport to board a Paris-bound flight.
He was taken to a police station in Harlem from where he was led away Sunday in handcuffs to a waiting police car and taken to an undisclosed destination. The police later clarified that the IMF chief had no diplomatic immunity.
In a statement, IMF chief's lawyer William W Taylor III said, "Strauss-Kahn will plead not guilty." Before the incident, it was being widely speculated that Strauss-Kahn, a Socialist politician, had a chance at beating incumbent President Nicholas Sarkozy, who is plagued with all time low ratings.
Observers and rivals have said that the alleged charges will ruin Strauss-Kahn's chances at a political career.
