The Worli cops investigating the mishap which claimed two lives after cement slabs fell from an under-construction building, have said part of a wall had fallen and not slabs from the balancing unit of a crane as reported earlier. The police have arrested three persons in connection with the incident, including a supervisor and two labourers.

On Tuesday night, two workers from a garment factory died when the slabs fell on them from the construction site of Worli’s Four Seasons Residency. The Worli cops filed a case under IPC Sections 304A (causing death by negligence) and 34 (common intention) against the contractor, supervisor and other concerned personnel on Wednesday night.
