Police on Friday recovered two mortar shells and a rocket launcher from a pond near Shaheed Shamsuzzoha Hall of Rajshahi University. A local boy found them around noon and informed police. Motihar Police Station’s Sub-Inspector Imran Hossain said the mortar shells and rocket launcher were kept at the police box near the Baddhabhumi area of the university. RU Proctor Professor Lutfor Rahman said there was a Pakistani army camp during the Liberation War where the mortar shells were found. “We suspect these to be from the Liberation War period,” he said. Shaheed Shamsuzzoha Hall was used as a camp by the Pakistani occupation force during the war. Recently, ammunitions, believed to be from that period, were found from a pond near the hall. Last week, another mortar shell was found from the same pond during excavation, which was destroyed by the army the next day.
