Ten fire tenders and hydraulic cranes were pressed into service to control the inferno at the factory of Excel Greenwich company in sector 11 of the industrial township, adjacent to the national capital.
Six badly-charred bodies have been recovered from the remains of the factory, an official told IANS.
Police suspect that an electrical short circuit triggered the fire and the flames rapidly spread to all the four floors in the building, leaving many with no chance to escape.
Some of the injured, who leaped out of the building in a bid to escape the flames, sustained serious injuries, with several admitted to nearby medical facilities with multiple fractures and serious spinal injuries.
