A woman who has accused former Apollo Global Management CEO Leon Black of sexual harassment and assault filed a lawsuit against him Tuesday in New York County Supreme Court, alleging that he behaved violently and coerced her to sign a nondisclosure agreement.

Former model Guzel Ganieva’s attorneys, Jeanne Christensen and Lindsay Goldbrum of the plaintiffs litigation firm Wigdor, argued that their client spent years enduring “a cycle of intimidation, abuse and humiliation by Black that on numerous occasions included forced sexual conduct against her will.”
