At one stage, one of the boys, Anik, brought a knife from his house and swooped on Hamim, leaving him critically injured. Another boy Wahzed also received injury when he tried to save Hamim.
Both, however, were taken to Pabna General Hospital where the doctors declared Hamim dead, the officer added.
