A man was killed and several others were injured in a clash between two groups of villagers in Mirzapur upazila on Friday.
The deceased, Azizul Miah, 30, a member of Bangladesh Army, was son of late Abdur Rouf Miah of Deobhog village under Mohera union in the upazila.
Azizul, who used to serve at Bogura Cantonment, came to the village early Friday, Officer in Charge (OC) of Mirzapur Police Station AKM Mizanul Haque said.
Police, however, detained five people from the spot for their alleged involvement in the clash.
Tension was prevailing among people of Uttarpara and Dakkhinpara for the last two days centring a rivalry between Rasel and Kamrul of the village, the OC said.
