Although no casualties have been reported yet, the owner of the factory told the firefighters that six of his employees were missing and were not responding to calls on their mobile phones, said Delhi Fire Services (DFS) chief Atul Garg.

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.

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.
