The four-member Bihar Police team, which arrived in Mumbai on July 29 to investigate Sushant Singh Rajput's death, have left the city, an official said.
The police team arrived to probe the 'abetment to suicide' case registered by K K Singh, the actor's father, in Patna against Rhea Chakraborty and others.
During their stay in Mumbai, the Bihar police recorded the statements of Rajput's sister, his former girlfriend Ankita Lokhande, Director Rumi Jaffrey, the late actor's flatmate Siddharth Pithani, his manager, cook and doctors among others, he said.
They also visited some banks to look into the financial transactions made from Rajput's accounts, he said.
"We collected good evidence in connection with the case and the Mumbai police cooperated with us," he added.
Meanwhile, Bihar Director General of Police Gupteshwar Pandey warned of legal action if Patna City Superintendent of Police Vinay Tiwari, who had gone to Mumbai to investigate the case, was not released from "forcible quarantine" by the end of the day.
Pandey expressed bewilderment over no positive response from the municipal authorities in Mumbai, whom he accused of keeping Tiwari in virtual house arrest, despite being informed about the adverse remarks made by the Supreme Court against their action.
Talking to reporters, DGP Pandey said he will consult Bihar's advocate general on the matter and, if Tiwari was not allowed to leave by Thursday, moving the court could be an option.
"It is virtual house arrest. Our officer went to Mumbai after informing his counterparts there in writing and over phone. I too had sent an SMS to my counterpart in Maharashtra informing him that Tiwari will be there for three days and shared with him the details," Pandey said.
"Tiwari had requested for an accommodation in the IPS mess, which was not granted. We let it go. But his forcible quarantine shortly after his reaching Mumbai is unacceptable. The IG, Patna Zone, wrote to the BMC chief quoting the guidelines of the Maharashtra government under which Tiwari could have been exempted from quarantine. It elicited no positive response," he lamented.
"When the Supreme Court also frowned upon the treatment meted out to Tiwari and called it unprofessional, the IGP again contacted the municipal authorities, but nothing came of it," DGP Pandey added.
