NAVI MUMBAI, Oct. 26 -- A bedroom ceiling came crashing down on a couple inside their Koparkhairane flat on Sunday, bringing chunks of concrete, plaster of Paris (POP) and broken steel reinforcement bars down on them. While both sustained injuries, the woman was left in critical condition. The couple, identified as Rakesh Gupta and Khushbu Gupta, were inside Room No. 1 of the flat at Plot No. 45 when the ceiling slab and POP collapsed. Residents rushed the injured couple to the Navi Mumbai Municipal Corporation's (NMMC) hospital in Vashi before the fire brigade arrived at the scene. Khushbu sustained serious injuries and was reported to be in critical condition. Their ages were not immediately available. The collapse was severe enough for fire officials to evacuate residents of the flat directly above the affected home as a precaution, after finding that the slab's steel reinforcement bars had also broken and fallen. Rohan Kokate, an NMMC fire officer, said the emergency call was received at 12.26 pm, and the fire engine reached the society gate at 1.20 pm. By then, residents had already taken the injured couple to hospital. The fire brigade asked all residents of Room No. 101, located directly above the affected flat, to move to a safe location. The team also informed Koparkhairane ward officer Bharat Dhande and handed over the site to ward office staff, police personnel and the society chairman....
