Commissioner of Police, Barrackpore police commissionerate, Niraj Singh said a call was received last night from locals about fire in a factory following which personnel from Dumdum Police Station and fire tenders reached the spot and doused the flames.
A body was found inside a room in the factory which was later identified to be of Sajal Kumar, the factory owner, police said.
"The body was unrecognizable. Only after washing it with water it was found to be of Sarkar's," a senior police officer investigating into the matter said.
In fact the doors of the room, where Sarkar's body was recovered from, was locked from outside, he said.
Sarkar's family alleged that he was "murdered" by some local promoters who were after the factory-land for quite sometime.
Based on Sarkar's family's complaint, a murder case against unknown persons have been initiated, police said, adding, they were waiting for Sarkar's postmortem report.
