Later, the body of Mansukh Hiren was fished out from Reti Bunder in Thane district's Mumbra.
Thane police registered an accidental death report and the body was sent for post-mortem at Chhatrapati Shivaji Maharaj Hospital in Kalva.
Maharashtra Legislature discusses the matter and the Opposition BJP demanded NIA probe into the incident.
Later, Maharashtra Home Minister handed over the probe to the state's Anti-Terrorism Squad.
In a significant development, the Anti-Terrorism Squad (ATS) said that they will probe a possible murder angle in the death of Mansukh Hiren.
The National Investigation Agency (NIA) took over the probe into the planting of the explosives-laden Scorpio SUV on March 8 which left the tri-party Maha Vikas Aghadi dispensation in Maharashtra fuming. CM Thackeray said that there was something “fishy” and hence the federal agency had taken over the investigation.
