In a strange development in the sexual assault allegations between French writer Tristane Banon and Dominique Strauss-Kahn, the mother of Banon is now saying she had "brutal" sex with the former International Monetary Fund chief in 2000 while they were both supposed to be working, reports The Daily Mail. 65-year-old Anne Mansouret said DSK "took me with the vulgarity of a soldier" during a consensual encounter at the Organization for Economic Coordination and Development where she worked as a special adviser.
