However, no casualty was reported in the incident, said a police officer.
As many as 14 fire tenders were rushed to the spot and it took them around two hours to douse the flames, after which a cooling operation was launched, said the officer.
The fire was so massive that the roof and a wall of the paan masala factory collapsed and fell over an Audi showroom-cum-workshop adjacent to it, said the officer, adding that the cause of the fire was yet to be ascertained.
