French prosecutors are considering whether to charge Dominique Strauss-Kahn with gang rape during a sex party he attended in Washington D.C.
The disgraced former International Monetary Fund (IMF) chief already faces charges of aggravated pimping in an organized gang for allegedly organizing orgies in France and the U.S.
But now magistrates have submitted new evidence that could result in Strauss-Kahn, two businessmen and a police chief facing the gang rape charge.
The Lille prosecutor was presented -- by the magistrates charged with investigating the prior 'Carlton affair' -- with a notice to make known, for whatever useful purpose, evidence of gang rape, a spokesman for Lille state prosecutor's office said on Friday, according to the Australian Associated Press.
It is understood the magistrates have only notified the prosecutor of some of the testimony points towards possible gang rape.
The prosecutor can now decide whether to throw out the allegation, or begin an investigation to establish if there is enough evidence to expand the original prosecution.
The allegations stem from oral evidence given by a Belgian prostitute who alleged she was forced to participate in an orgy against her will in a Washington hotel suite in 2010.
But despite the fact another prostitute also present confirmed the story, neither has sought to press charges.
Strauss-Kahn was hauled from a France-bound flight in New York last May, after he was accused of sexually assaulting a maid in his hotel room.
The case later collapsed after doubts emerged about the maid's testimony, however she is still pursuing a civil case against him.
