A major portion of the factory has been badly damaged due to the devastating fire and the building has been declared as dangerous by the Municipal Corporation, the fire department added.
A total of 31 fire tenders and more than 100 firefighters were pressed into service to douse the flames, fire department officials said, adding that two people, who were missing earlier, have been rescued.
The cause of the fire is yet to be determined and the shoe factory lacked fire safety measures, the officials said.

The factory was shut, however, the owner of the factory said 4-6 people are missing as they are not answering phone calls, search operation is still underway. However, no body has been recovered so far,” Garg added.
