Extensive damage was caused to a spices manufacturing unit at Khapuria industrial estate here on Sunday morning when a part of the unit, housing a boiler plant, caught fire. Properties worth over crores of rupees are believed to have gutted.

According to sources, a three-storied building of the spices unit caught fire around 4 a.m. while some workers were working inside the plant. The security staff of the company initially tried to douse the flame with their in-house fire extinguisher provisions but when they failed to control it, the fire-brigade personnel were informed.

At least four fire tenders took nearly four hours to bring the fire under control. But by that time the unit had suffered massive damage.
