The investigation into actor Sushant Singh Rajput's death flared into a tug of war between the Bihar and Mumbai Police on Friday while the Enforcement Directorate, which probes financial crimes, filed a money laundering case against his girlfriend Rhea Chakraborty, also an actor, and her family. The case was filed after the agency took note of an FIR by Bihar Police, which is investigating the Rs 15 crore transaction from the actor's account and proceeds from the alleged crime, as claimed by his family. "The source of information with the father, we don't know. I have been looking at their accounts for one year, there are no such transactions," Sushant Singh Rajput's chartered accountant Sandeep Sridhar told NDTV.
