Md Khorshed Alam, Executive Engineer at the Local Government Engineering Department (LGED) in Manikganj, said the school disappeared into the mighty river on Saturday afternoon.
Locals said the water level of the Jamuna had risen significantly in recent days, resulting in a powerful flow that led to erosion along the riverbank.
Wazed Ali Sarkar, member of Ward No. 5 under Bachamara Union, said while some furniture, including chairs and table, was saved, heavier items such as steel furniture could not be salvaged, reports UNB.
Nahiyan Nuren, Upazila Nirbahi Officer (UNO) of Daulatpur, said after being alerted about the erosion on Friday, a local engineer was sent to inspect the school.
