French writer Tristane Banon is to file a lawsuit for attempted rape against former IMF chief Dominique Strauss-Kahn, her lawyer says.
The lawyer, David Koubbi, said the suit referred to an incident in 2003 when Ms Banon went to interview Mr Strauss-Kahn in a flat in Paris.
Mr Strauss-Kahn was recently freed from house arrest in New York in a separate alleged sex assault case.
He denies assaulting a hotel maid in the US city on 14 May.
It was shortly after Mr Strauss-Kahn was arrested in New York that Ms Banon came forward to say that he had tried to assault her.
