An investigation into the Mumbai BMW hit-and-run case revealed that the woman was dragged for 1.5 km by Shiv Sena leader Rajesh Shah's son Mihir, an official said. "Mihir and [driver Rajrishi Bidawat] stopped the car...and removed the woman who'd got entangled in...vehicle's tyre," the official added. Bidawat then ran over the victim again while reversing, the official further said.
