A drug addict youth killed his minor son allegedly over a family feud for money in Phulbari upazila of the district yesterday.
Villagers, however, caught culprit Subash Chandra Mohanta, 28, son of Sunil Chandra Mohanta of Barai village, and handed him over to the police.
Anita Mohanta, mother of the 22-month-old victim Babu, said her drug addict husband often used to torture her for money since their marriage two years ago.
On Wednesday afternoon, Subas demanded some money from her for buying drugs.
When she refused to give him the money he physically tortured her, she said, adding that her parents were supposed to visit her house yesterday morning to settle the matter.
But around 7:00am, Subash stabbed his son to death with a knife, when she went out for her work and started behaving abnormally, Anita alleged.
Locals rushed to the house, caught Subas from the spot and informed the police.
On information, police went to the spot, recovered the body and sent it to M Abdur Rahim Medical College Hospital for autopsy, Officer in Charge of Phulbari Police Station Fakhrul Islam said.
A case was filed with the police station accusing Subas the same evening, he added.
After the murder a pall of gloom descended the locality.
