A BCL leader and another college student were seriously stabbed by a group of youths over past enmity at Akhaura Shaheed Smrity College in the district yesterday noon. The injured two are Shamim Molla, upazila convener of BCL and Shafiqul Alam Bari, a second year student of the college. According to college and police sources, on Saturday, Shafiqul Alam Bari slapped one Mushfiqur Rahman of his class following an altercation over a trifling matter. When Shamim Molla and BCL college secretary Shafikuzzaman Lion sat with them to resolve the problem, Mushfiqur along with his group and some outsiders stabbed Shafiqul Alam Bari. As Shamim tried to resist the attackers, they also stabbed him. Both were admitted to Brahmanbaria Sadar Hospital in critical condition.
