Sushant Singh death: Mumbai police halt investigation due to Bihar police's probe

In the Sushant Singh Rajput case, Bihar police have initiated the investigation in Mumbai after Sushant's father got an FIR registered against Rhea Chakraborty. 

So Mumbai police have halted the investigation and are in a wait and watch mode. The Mumbai police will not be recording any more statements till Bihar police are done with their probe.

This may be unfortunate for the case as Mumbai police were about to have Karan Johar's statements recorded soon.
