Unidentified miscreants slaughtered a businessman at Zianagar under Dupchachia Upazila in Bogra on Wednesday night.
Reazuddin Ahmed, officer-in-charge of Dupchachia police said the victim, Mizanur Rahman Liton, a potato trader, was killed over land conflict with his rivals.
The locals, however, said Liton was always active against drug related businesses and often raised his voice against people involved in the business.
Some four to five persons attacked Liton with sharp weapons on his way home from his shop at Nihali Bazar around 11pm.
The attackers left his body on the street after slaughtering him there, locals said.
Police arrested three persons -- Akam Uddin, Mofazzal Moka and Bayezid -- in connection with the murder.
