Strauss-Kahn files legal action over tell-all book

Disgraced IMF chief Dominique Strauss-Kahn is taking legal steps to stop a controversial new book by Argentinian-born Marcela Iacub detailing their liaison, his lawyers said on Monday.

In "Beauty and the Beast," due to be released on Wednesday, Iacub says she had a relationship with Strauss-Kahn from January to August 2012, in the midst of the scandal over accusations he sexually assaulted a New York hotel maid the previous year.

She doesn't name Strauss-Kahn in the book, but she told Le Nouvel Observateur magazine that it was about him.
