A local Jubo Dal leader was hacked to death by some miscreants at Siladi in Sadar upazila on Thursday night.
The deceased was identified as Sabuj Hossain, general secretary of no 1 Siladi union unit Jubo Dal and son of Abu Taher of the area.
Quoting local people, police said a group of miscreants intercepted Sabuj and hacked him to death while returning to his home from his poultry farm around 11:30 pm.
Hearing hue and cry, local people rushed in and caught five miscreants and gave them a good thrashing while fleeing the spot after the murder.
Later they were handed over to police.
They were identified as Belal Hossain, a local Islami Chhatra Shibir activist, his father Jaher Ahmed, his brother Riaz Hossain, Arif Hossain and Mahiuddin.
