Dominique Strauss-Kahn's alleged sex scandals are making headlines again. The former IMF chief will be questioned next week by police investigating a prostitution ring in northern France, according to officials. Strauss-Kahn has been summoned for questioning on Tuesday in Lille about his involvement in the alleged prostitution ring and organizing sex parties at luxury hotels in the city. Calling on prostitutes is technically legal in France, though it's illegal to pimp them out to others. Reuters reports that Strauss Kahn's lawyer previously said the ex-IMF chief believed he was participating in swingers' parties and was unaware that the women involved were prostitutes. Though he still faces a civil suit by Nafissatou Diallo, the New York City Sofitel maid who accused him of rape, Strauss-Kahn has demanded to be questioned by judges about his involvement in the alleged prostitution ring with the hope that it will clear his name.
