As a sequel to their long rivalry, the family members of Julhash assaulted Dulal on 16 December last year over the issue.
Later, Dulal’s father Mujibur lodged a complaint against nine people, including Julhash, and police arrested Julhash in this connection.
On 12 January, Julhash was freed from jail after securing bail in the case.
When Julhash went to the bus stand area for having tea in the evening, 8-10 people, led by Dulal, swooped on him and stabbed Julhash indiscriminately, leaving him critically injured.
He was taken to Enam Medical College and Hospital where doctors declared dead in the night.
On information, police went to the spot and arrested Mujibur in this connection, said OC.
