Overview
- The roof of a three‑ to four‑storey warehouse under construction in Taratala collapsed during casting work on Wednesday, burying workers beneath heavy iron beams and hardened concrete.
- Rescue and recovery involved Kolkata Police Disaster Management Group, NDRF, SDRF, fire services and the Indian Army using cranes, gas cutters, sniffer dogs, drones and ground‑penetrating radar to reach survivors and recover bodies.
- Kolkata Police registered a suo motu FIR, formed a Special Investigation Team and arrested six people including the structural fabricator, site supervisor and the land lessee as the official death toll climbed to 11 and 19 injured remained at SSKM Hospital.
- The West Bengal government ordered a suspension of projects approved under the former Kolkata Municipal Corporation until July 31, launched a multi‑agency audit of sanctioned plans and announced ₹10 lakh for each family of the deceased and ₹1 lakh for the injured.
- Preliminary engineering checks and on‑site officials cited prima facie failures in design and construction — notably insufficient iron‑beam capacity, absent bracing and alleged substandard casting materials — and the absence of an attendance register has hindered an exact count of workers present.
