Former IMF head and the Sofitel's most infamous guest Dominique Strauss-Kahn is under investigation by authorities in his native country for his involvement in a prostitution ring. BBC News reports that authorities have summoned him for questioning next week, and he can be detained for as long as 48 hours.

While having sex with a prostitute is legal in France, providing prostitutes for others is not, and the French media has implicated Strauss-Kahn in the "Carlton Affair" (named for the hotel in Lille where the "sex parties" allegedly occurred) for months. Strauss-Kahn, through his attorney, has denied having any knowledge that the women were prostitutes, and claims he believed he was attending "swingers' parties."

Several businessmen and police chiefs have been arrested for their relationship to the prostitution ring. Strauss-Kahn still faces a civil suit from Nafissatou Diallo, the maid who claimed he sexually assaulted her at the Sofitel last May. Charges were dropped by the Manhattan DA's office due to questions surrounding Diallo's credibility. Then again, it was probably all a set up anyway.
