New Delhi, Aug 12 (ANI): Lawyer of late actor Sushant Singh Rajput’s father, Vikas Singh on August 12 stated that the role of his son’s friend and roommate Siddharth Pithani in Sushant’s death case is “extremely dubious” and that he is a very “intelligent criminal” He said, “Siddharth Pithani is extremely dubious. He is a very intelligent criminal. What he did was, until FIR was registered by family he was talking to them regularly and trying to help them. The moment FIR was registered, he started helping Rhea.” “The way he has behaved after registration of FIR, the way he is writing email to Rhea when she's a named accused. Helping a named accused in this manner shows complicity between Rhea and him. It is only upon custodial interrogation that the real truth will come out,” he added.
