The incident took place during the wee hours yesterday.
"Exact loss is being ascertained. The charred body of a person could not be identified so far," fire station officer Vijai Prakash said.
Five fire tenders were used to douse the blaze that engulfed nearly two dozen grain shops made of bamboo strips, he said.
"The cause of the fire is being enquired. However, investigation so far reveal that probably the victim had thrown a half-burnt bidi in the shop made of bamboo strips," the official said.
