Five labourers died and 20 were injured after a three-storey under-construction private warehouse in West Bengal's Taratala area of west Kolkata collapsed on Wednesday afternoon.
Chief Minister Suvendu Adhikari said that the Kolkata Municipal Corporation (KMC) indicated the building plan was flawed and possibly passed by the Trinamool Congress (TMC)-controlled civic body in exchange for money.
Rescue operations by police, KMC, and the fire brigade department started at 12.45pm, and the army and National Disaster Response Force (NDRF) joined the operation between 1.30 and 2pm.
Around 12-14 people are still trapped under the debris, and cranes and gas cutters were used to remove the steel and concrete beams.
CM Adhikari said that the KMC building department has initially told him that the plan is flawed, and the details will be revealed during investigation.
