Mumbai: A day after three civic workers fell from a crane that was trying to extricate them from a 20-foot-deep sewage pit near IIT Mumbai's main gate in Powai and died - the Powai police has registered a FIR against the accused and arrested one person for not taking precautions and compromising the safety of workers under section 304a (death due to negligence) of the IPC.

The police has sought details from the civic authority as to which supervisor/contractor was assigned the work of the main sewer line opposite IIT Powai. A probe into the death of the three contract labourers who died on Monday after the crane's pulley snapped is underway.

Police sources said that what was initially registered as an accidental death report (ADR) has been changed into a FIR against the supervisor/contractor. The police arrested one Mohammad Irrfan Mohammad Tahir Khan (24) for allegedly taking no precautionary measures to ensure the workers' safety.

Navainchandra Reddy, deputy commissioner of police zone 10 said, "A case has been registered and the accused arrested. The arrests have been made under section 304A of the Indian Penal Code which pertains to causing death by negligence. We have a sought an enquiry and details from civic authorities as to who was assigned the work."
