Mr Strauss-Kahn’s lawyers say he is the victim of a “lynching campaign”
A French prosecutor has ordered an initial inquiry into claims that ex-IMF head Dominique Strauss-Kahn was involved in “gang rape” in Washington.
The allegations come from a Belgian prostitute who said she was at a hotel sex party in the city in December 2010.
Mr Strauss-Kahn, 63, is already under investigation with three other men over their alleged roles in a prostitution ring. He denies the allegations.
A charge that he attempted to rape a US hotel maid was dropped last year.
But the case put an end to Mr Strauss-Kahn’s career at the International Monetary Fund and dashed his hopes of running as Socialist candidate for the French presidency.
