Another mortal shell was recovered from a pond on Rajshahi University campus on Friday.
Maruf Hossain, a local youth, found the mortar shell in the pond adjacent to the RU Agriculture Faculty, while he was washing his face with the pond water around 8am.
Being informed, police rushed to the spot and recovered the shell and subsequently disposed of the shell.
Earlier, seven mortar shells and a rocket launcher were recovered from the bottom of an excavated pond beside the RU's Shaheed Shamsuzzoha Hall.
RU Proctor Professor Prof Asabul Haque told BSS that the recovered mortar shells and rocket launcher were quite old and the new one is also the same as the earlier ones.
He said Shaheed Sahmsuzzoha Hall is located near the pond. The shell might be from the time of the Liberation War in 1971, as the dormitory was used as a camp by the Pakistani Army during the War.
