Strauss-Kahn freed by police

The former chief of the International Monetary Fund (IMF), Dominique Strauss-Kahn, has been released from a French police station after two days of questioning over a suspected hotel prostitution ring.

Judicial officials say he will be summoned again next month by three judges who will decide if there is enough evidence to file charges in a case centring on the alleged prostitution ring in France and Belgium.

French TV footage showed police holding reporters behind metal barriers as a tinted-window car carrying Strauss-Kahn left the police station in the northern city of Lille.

Strauss-Kahn was a one-time French presidential hopeful whose political chances were derailed by a sexual assault accusation in New York City and his subsequent resignation from the IMF in May.
