"No one reportedly died in the incident yet. Injured included the workers at the scrap godown and others around who were attempting to douse the fire."
The officer said the exact reason behind the incident is yet to be ascertained.
Asked if any cylinder exploded inside the godown which caused the huge fire, the officer said: "Some cooking gas cylinders have been recovered from the spot but none of them exploded. It is a matter of investigation if the fire spread because of the leakage of gas from any one of these cylinders."
