MUMBAI, Aug. 21 -- The Gamdevi police registered a case on Thursday after a family member of a labourer, who died on August 3 while working at the Cadbury House construction site in Mahalaxmi, filed a complaint alleging negligence by the supervisor and crane operator. The deceased was identified as Mohammad Sakir Suban, 45, a resident of Saat Rasta in South Mumbai. His uncle, Abu Rafique, filed the complaint. Police said both the uncle and nephew worked at the site where Strong Built Private Limited was constructing a multi-storeyed building with luxury apartments. On August 3, the belt of a crane carrying a heavy iron beam snapped, causing the beam to fall on Suban. "Suban was trapped under the beam after the crane belt broke. He was rushed to BYL Nair Hospital where he was declared dead on arrival," said an officer from Gamdevi police station. "We registered a case against site supervisor Sachin Achyut Kamthekar and crane operator Vijay Kumar, after the family approached us on Thursday after completing the last rites at their native place. A notice was served to Kamthekar." The case was registered under section 106 (causing death by negligence) of the Bharatiya Nyaya Sanhita (BNS)....
