“Since this was an abandoned building, no one was inside when a portion of the building’s roof collapsed,” said an officer leading the DMG team. Personnel from the Disaster Management Group (DMG) posted in Bhowanipore rushed to the spot and cordoned off the area before launching a clean-up drive using shovels and crow-bars. The police said portions of the house in Bhowanipore - opposite Jadu Babu’s Bazar, behind India Club - collapsed when the rain nearly stopped.Ĭovered with trees and shrubs, the concrete boundary wall of the building did not appear weak from outside. Three hours earlier, a portion of the roof of an old three-storey building in Gopal Chandra Lane in Bowbazar in central Kolkata had collapsed.
