Local people and witnesses said, the incident occurred when a rival group, reportedly led by Sekander and Azam, attacked the families in an alleged move to capture the lands.

They rival groups used lethal weapons. Some gunshots were also heard, witnesses said.

Being informed, Rab (Rapid Action Battalion) personnel and police from Bayezid thana rushed to the spot. The attackers fled away.

Police later picked up three persons-- Alamgir, Azizul and Abul Kalam-- from the spot.
