Dominique Strauss-Kahn, former chief of the International Monetary Fund (IMF), has been questioned by French police as a suspect in a prostitution ring inquiry, a prosecutor has said.
Strauss-Kahn is being held in custody at a police station in Lille, northern France, the BBC reported on Tuesday.
Police have questioned a number of prostitutes who have admitted having sex with Strauss-Kahn. But he insists he did not know that those women were prostitutes.
According to French media, he could be held by police for up to 48 hours.
