The chief of Bihar police commented on the progress in the investigation into actor Sushant Singh Rajput's death. DGP Gupteshwar Pandey said that the probe team visiting Mumbai was yet to receive important documents like forensic and autopsy reports from Maharashtra police. He added that he's sure that Mumbai cops will cooperate in the probe and the case will move further when such information and documents are received. A day earlier, Bihar deputy CM Sushil Kumar Modi had alleged that Maharashtra government was under pressure from a Congress-backed 'Bollywood mafia' to let those involved in the Sushant case go scot-free. The Bihar police is also looking for Siddharth Pithani, Sushant's flatmate, who had earlier written to the Mumbai police that the late actor's family was pressurising him to give a statement against Rhea Chakraborty. Sushant Singh was found dead at his Mumbai house on June 14. His father has accused his girlfriend Rhea of wrongfully confining him and also taking crores of Rupees from him.
