A former JPMorgan banker accused of making explosive sexual harassment claims against a senior executive has hired a high-profile New York lawyer best known for representing Jeffrey Epstein’s accusers.Indian-origin former Wall Street analyst Chirayu Rana is being represented by Daniel Kaiser of law firm Kaiser, Sauerborn & Mayer. Kaiser has previously acted for several women who brought claims against convicted sex offender and pedophile Epstein, who died in 2019.Rana has sued JPMorgan Executive Director Lorna Hajdini, alleging she drugged him with Viagra and repeatedly sexually assaulted him. The claims were rejected by the bank and Hazdini.The lawsuit details a series of disturbing allegations, including allegations that Hajdini used drugs and coercion to control her. However, JPMorgan says an internal investigation found no evidence to support the claims. A spokesperson said that Rana refused to fully cooperate with investigators and refused to provide important supporting details. Hajdini has also rejected the allegations through his lawyers.According to the Wall Street Journal, JPMorgan had previously offered Rana about $1 million to settle the dispute, but he rejected it and demanded more than $20 million instead.Rana’s attorney Kaiser told The New York Post: “A motion was filed today seeking an order allowing my client to proceed by John Doe. Attached to those papers are corroborating evidence of his claims. And there’s more.”Kaiser has also said that he expects the case to escalate as more evidence is presented.The controversy has also drawn attention because of Kaiser’s legal background, which includes representing Epstein’s accusers such as Jennifer Araoz, who sued Epstein’s estate and associates after long-running abuse allegations.JPMorgan said its own internal review, which included examining emails and work records, found no authenticity to Rana’s claims. The bank also noted that Rana and Hajdini worked under different reporting lines, meaning it had no control over their compensation or pay.Colleagues have previously described Rana as “socially awkward”, while Hajdini is internally considered a strong performing executive in the finance team.
