JPMorgan seeks dismissal of ex-banker's lawsuit as sister recants

• Chirayu Rana, a former JPMorgan banker, filed a lawsuit accusing a female executive of forcing him to become her'sex slave'.
• JPMorgan claims Rana pushed his sister and a friend to lie in support of his sexual assault case.
• Rana's sister has recanted her support, and a third law firm has asked to drop him as a client.
• An Oct. 23 court filing reviewed by Fortune reveals these developments.
• This marks potentially Rana's third change in legal representation since the case began.
