A former JPMorgan banker accused of making explosive sexual harassment claims against a senior executive has hired a high-profile New York lawyer known for representing accusers of Jeffrey Epstein.Chirayu Rana, an Indian-origin former Wall Street analyst is being represented by Daniel Kaiser of the law firm Kaiser, Saurborn & Mair. Kaiser has previously acted for multiple women who brought claims against Epstein, the convicted sex offender and pedophile who died in 2019.Rana has sued JPMorgan executive director Lorna Hajdini, alleging she drugged him with viagra and subjected him to repeated sexual assaults. The claims were denied by the bank and Hajdini.The lawsuit describes a series of disturbing allegations, including accusations that Hajdini used drugs and coercion to control him. However, JPMorgan says an internal investigation found no evidence supporting the claims. A spokesperson said Rana refused to fully cooperate with investigators and declined to provide key supporting details. Hajdini has also rejected the allegations through her lawyers.According to the the Wall Street Journal, JPMorgan previously offered Rana around $1 million to settle the dispute, but he rejected it and instead sought more than $20 million.Rana’s lawyer Kaiser told The New York Post: “A motion was filed today to seek an order to permit my client to proceed by John Doe. Those papers attach corroborating evidence of his claims. And there is much more.”Kaiser has also said he expects the case to develop further as more evidence is presented.The dispute has also drawn attention due to Kaiser’s legal background, including his representation of Epstein accusers such as Jennifer Araoz, who sued Epstein’s estate and associates following allegations of long-term abuse.JPMorgan has said its own internal review included examination of emails and work records and found no authenticity of Rana’s claims. The bank also noted that Rana and Hajdini worked under different reporting lines, meaning she had no control over his compensation or salary.Colleagues have previously described Rana as “socially awkward”, while Hajdini is regarded internally as a strong-performing executive on the finance team.
