Dorjee Tsering, a scrap dealer was trying to extract lead from the discarded object, probably believing it a defunct bomb, with a hammer when the object went off, Tawang police station officer in charge S Monpa informed over telephone today.
The object, suspected to be a misfired bomb from the firing range of Indian Army, was spotted from a nearby jungle where the scrap dealers often go to collect discarded ammunition of the forces, the officer said.
