Ex-IMF chief Dominique Strauss-Kahn and the French writer who accuses him of attempted rape have confronted each other as part of a police inquiry.Police are investigating Tristane Banon\'s complaint before prosecutors decide whether to press charges.Mr Strauss-Kahn is said to admit making \"an advance\" on Ms Banon, but denies any violence, and is suing for slander.She made the allegations in June, when Mr Strauss-Kahn was accused of rape in New York; that case was later dropped.The confrontation took place at a Paris police station without lawyers present, but with police officers in the room.Police confrontations are held when two people in a case give different versions of events.Mr Strauss-Kahn left the police station a couple of hours after arriving without making any comments.
