The deceased was identified as Sazzad Hossain Shakil, 25, joint secretary of Alkara union unit of BCL and son of Saleh Ahmed alias Badhu Miah of Kulsar village in Chouddagram upazila.
Golam Faruque Helal, organising secretary of upazila Awami League, said a group of miscreants intercepted a bus at Padua on Dhaka-Chattogram highway in the morning while Shakil was going to the district town by it to appear before a court in a case.
The hoodlums dragged the BCL leader out of the bus and took him to Feni in a microbus where they beat him mercilessly with iron rods and hammers, leaving him critically injured.
Later, he was taken to Feni Sadar Hospital where doctors referred him to Dhaka Medical College Hospital. However, Shakil died on the way to the hospital in the afternoon.
Abdullah Al Mahfuz, officer-in-charge of Chouddagram Police Station, said they were looking in to the incident.
