Former International Monetary Fund chief Dominique Strauss-Kahn is being questioned by French police investigating a suspected hotel prostitution ring. Strauss-Kahn arrived Tuesday at a police station in the northern city of Lille. Police are investigating a suspected prostitution ring in France and neighboring Belgium that has implicated police and other officials. Strauss-Kahn\'s name surfaced in the investigation last fall. His lawyer asked that Strauss-Kahn be allowed to tell his side of the story. Strauss-Kahn was accused last year of attacking a New York hotel maid. The case was dismissed after prosecutors said they lost faith in the accuser\'s credibility. In the new case, authorities have questioned prostitutes who said they had sex with Strauss-Kahn during 2010 and 2011 in France and Washington, D.C.
