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.
