PARIS (Reuters/AFP) - A French writer will file a legal complaint against former IMF chief Dominique Strauss-Kahn on Tuesday alleging that he tried to rape her during an incident nine years ago, her lawyer told Reuters. Lawyer David Koubbi said the complaint by Tristane Banon, 32, would relate to an incident that took place when she went to interview Strauss-Kahn, a former French finance minister, in an apartment in Paris. She was 22 at the time. "Tristane Banon will file a complaint on Tuesday for attempted rape in Paris," Koubbi said. "These acts are extremely serious," he added. "These events were combined with a violence that was absolutely striking for these kinds of situations." Meanwhile, former IMF chief Dominique Strauss-Kahn will sue for slander a French woman accusing him of attempted rape, his lawyers said in a statement Monday. Strauss-Kahn had taken note of journalist Tristane Banon's intention to lodge an attempted rape complaint against him, the lawyers said, dismissing the claims as "imaginary" and adding they were "in the process of compiling a libel complaint" against Banon. Koubbi would not say whether the timing was affected by the developments in NY, which suggest the case there is unravelling. Until his May arrest, Strauss-Kahn, who was seen as the left's best chance of winning the 2012 election. Under French law, a complaint of attempted rape can be brought up to 10 years after an alleged attack, whereas sexual assault charges expire after three years. Koubbi had said several times in recent weeks that his client was considering taking action against Strauss-Kahn for the incident, which he said on Monday took place in early 2003, not in 2002 as had previously been reported. Baron's mother Anne Mansouret, a Socialist councilor, has said she regrets talking her out of filing a complaint at the time. The incident first surfaced publicly in 2007, when Banon discussed it in graphic detail on a television talk show, albeit with Strauss-Kahn's name bleeped out. During the TV talk show, which has been widely circulated online in recent weeks, Banon said he had insisted on holding her hand during the interview before making advances that led to her fighting him off as he tried to undo her clothing.
