The deceased was identified as Tofazzal Hossain Rana, son of Abdullah Fakir of the village.
Mahsin, officer-in-charge of Raipura Police Station, said supporters of former Bashgari union chairman and ex-union AL president Shahed Sarkar and current chairman Sirajul Haque, also an AL leader, had been at loggerheads over establishing supremacy in the area.
As a sequel to the enmity, the supporters of both groups attacked each other and exchanged gunfire from around 9 pm to 12 am on Thursday.
After a short interval, they again exchanged gunfire early Friday.
Tofazzel, who came out of his home to respond to natural call, sustained bullet injuries in his head around 6 am during the gunfight. Later, he died on way to Narsingdi hospital.
A tense situation was prevailing in the area following the clash.
Additional police have been deployed in the area to avert further trouble.
