Sushant Singh Rajput, 34, was found dead in his Mumbai apartment on June 14. The Mumbai Police said it was suicide and has questioned over 50 people on allegations that the actor was suffering from depression and had felt sidelined because of cut-throat rivalries in the film industry.
Mr Rajput's father has accused actor Rhea Chakraborty of illegally transferring Rs. 15 crore in tranches from his son's account and of driving him to suicide. She and her family were questioned by the Enforcement Directorate on Monday. The agency's probe focuses on Ms Chakraborty's income, investments, business and professional deals.
On Tuesday, another sister of Mr Rajut, Meetu Singh, was questioned by the Enforcement Directorate in connection to their investigations into the possible money laundering case against Rhea Chakraborty. Mr Rajput's friend and roommate Siddharth Pithani and his business manager Shruti Modi were also questioned in connection with the case.
Ms Chakraborty has filed an affidavit with the Supreme Court, complaining against media reports that have "blown out of proportion" ongoing investigations into Mr Rajput's death.
