Kolkata: On Thursday, a man was killed and two others injured in a bomb blast inside an electrical repair shop in Durgapur of West Bengal's Burdwan district, police said.

"One man has been killed and two others received some injuries. Prime facie it appears to be a crude bomb explosion," said Commissioner of Police, (Asansol-Durgapur), Ajay Kumar Nand.

The owner of the shop has been arrested.

While people initially presumed the cause of the explosion to be the compressor of a refrigerator bursting, police upon inspection found shrapnel and recovered two more container shaped bombs.

"The two bombs have been defused and samples sent for forensic testing. As of now, it seems they are not IEDs as there was no trigger mechanism in them. We are probing the matter and awaiting the forensic test reports," added Nand.

The man who died has been identified as Pappu Ram, 35.

A forensic team is slated to visit the site on Friday.
