A case under relevant provisions of the Arms Act had been registered against Sarvankar, his son Samadhan and their supporters. The MLA from Mumbai's Mahim constituency is a member of the Shiv Sena faction headed by Chief Minister Eknath Shinde. "The ballistic report has found the shot fired inside the Dadar police station campus was from Sarvankar's licenced weapon. The weapon was seized at the time and sent for analysis at the Forensic Sciences Laboratory in Kalina," said the official.
