The motorcycle, which was abandoned near Mount Mary Church, a little over a kilometre from the actor’s house, was registered in the name of a man living in the Panvel area of Navi Mumbai, the official said.

The police have formed more than a dozen teams to probe the incident, and some have been sent to Bihar, Rajasthan and Delhi, the official said.
“So far, we have not arrested or detained anybody in the case, but our inquiry is going on with several people,” he said.
The police have registered a first information report (FIR) against an “unidentified person” under section 307 (attempt to murder) of the Indian Penal Code (IPC) and the Arms Act.
