A 14-year-old boy was stabbed to death allegedly by his younger brother following a dispute over the death of a pet bird in Lakshmipur on Wednesday.

The deceased is Al Amin, son of Jafar Ahmed of a village in Sadar upazila.

According to police and locals, Al Amin’s younger brother, aged 10, had been grieving since Wednesday morning after his pet bird was killed by a cat.

When Al Amin asked him to stop crying, an argument broke out between the two.

At one stage, the younger brother brought a knife and stabbed Al Amin in the chest, leaving him injured.

Family members rescued the boy and took him to a Noakhali hospital, where he died while undergoing treatment.

Additional superintendent of police of Lakshmipur Hossain Mohammad Raihan Kazemy said they were taking necessary legal action in this regard.
