A Secondary School Certificate (SSC) examinee was shot dead during a clash between two factions of Awami League at Bashgari under Raipura upazila of Narsingdi early Friday.
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.
