In a turn of events that will throw French politics into turmoil, the head of the International Monetary Fund, Dominique Strauss-Kahn, was removed from an airplane at Kennedy Airport on Saturday and arrested on charges of rape. Law enforcement officials say Strauss-Kahn allegedly forced a cleaning woman at his Times Square hotel into his bed and sexually assaulted her. He allegedly allowed the woman to leave before departing for the airport. Strauss-Kahn left belongings behind in his hotel room, including his cellphone, and authorities say he did not resist being taken into custody when they boarded his Paris-bound flight just before takeoff. He has pleaded not guilty to the charges. Strauss-Kahn was seen as the strongest challenger to the conservative and unpopular President Nicolas Sarkozy, and was expected to seek the Socialist Party nomination by the end of May.
