Billionaire Marc Lasry has filed a lawsuit against former employee Gina Strum, accusing her of attempting to extort $50 million by threatening to disseminate false information about him and his firm, Avenue Capital Group. Strum, who worked in business development for four years, allegedly warned that the situation could become "really, really ugly" unless she received a payout. Lasry's suit was filed in New York state court, with his sister Sonia Gardner also named as a co-plaintiff.
