Two workers died after the mezzanine floor in an under-construction factory collapsed on Saturday, in Bhandup. Locals said they found the youth under the debris. Doctors of a civic-run hospital said they appeared to have suffocated. Police have detained three people, including the owner.

Doctors at civic-run M T Agarwal hospital in Mulund declared Rajkumar Sahay, 21, and Ramavtar Arjun Yadav, 18, dead on Sunday morning when the incident was reported. Seema Mishra, a resident, said the workers sleep in the factory on most days. Around 7 am, when they did not come out of the factory, another factory worker slammed the shutter of the shop.
