Naogaon: Seven ‘wartime’ grenades and 47 bullets were recovered from a septic tank of Naogaon Sadar Hospital on Friday afternoon.  

Naogaon Police Station officer-in-charge M Jakirul Islam said hospital authorities engaged workers to remove three old septic tanks in order to construct a new building there.

At one stage, the workers found a hand grenade inside a septic tank at about 1:00pm whereby the authorities postponed the digging work and informed Naogaon Sadar Model Police Station.  

Later, a team of police rushed in and recovered seven hand grenades and 47 bullets of Chinese rifle from the tank.

OC Jakirul said Pakistani soldiers might have left the ammunition during the Liberation War in 1971 as a Punjab monogram was inscribed on them.

The hand grenades and the bullets were taken to the police station.
