Gurugram, June 25 -- At least three construction workers were injured, one of them critically, after a portion of a house collapsed onto an adjacent under-construction basement in Gurugram's Sector 10 late Monday evening, police officials said. The critically injured worker, identified as Surender Kumar from Tikamgarh, Madhya Pradesh, was rescued after a two-hour operation involving the State Disaster Response Force (SDRF) and is undergoing treatment at the Sector 10A civil hospital. The incident occurred between 8.30pm and 9pm at a residential plot in Basai, where basement excavation was underway. Police and disaster management officials said the collapse was triggered due to alleged negligence during digging. Mohit Sharma, chief warden of Gurugram Civil Defence, said two workers were quickly pulled out by co-workers using bare hands. "However, Surender was trapped several feet deep in a narrow spot with large concrete chunks over him," Sharma said. "Only his head was visible, allowing him to breathe." Inspector Sandeep, SHO of Sector 10 police station, said, "No complaint has been received. If the worker's family alleges negligence, an FIR will be registered."...
