A second woman has come forward with allegations of rape against Leon Black, the billionaire co-founder of Apollo Global Management, claiming in court documents filed late Monday she was raped by the private equity giant inside Jeffrey Epstein’s Manhattan townhouse two decades ago—allegations Black’s lawyers have dismissed as a “complete fiction.”  The claims from the woman, identified as “Jane Doe,” were filed as part of an ongoing civil lawsuit against Black launched earlier this year by Guzel Ganieva, a former Russian model who alleges she was forced into a years-long sexual relationship with Black, allegations that Black denies.
