A 22-year-old housewife was stabbed and burnt to death by her husband over his extramarital relationships in Narail Sadar on Friday.
The deceased is Achhiya Begum, 22, wife of Rony Sheikh, 26, of Saratala village under Sadar upazila of the district.
Police and locals said Rony got married to Achhiya around four years back with consent of family but later he maintained extramarital relationships with other girls.
The couple having a minor son used to quarrel with each other over the issue often, they said.
Similarly on Friday noon, an argument broke out between them over the issue and Rony stabbed her with sharp weapons and left the house after setting her on fire.
Noticing smoke from the house, neighbours rushed to the house and found her dead and burnt. The child was out of the residence during the incident.
Mahmudul Rahman, officer-in-charge of Narail Sadar police station, said that he suspects Rony in a planned way killed his wife over the extra marital relationship.
Some valuables of the house were also burnt in the fire, he said, adding that the body was sent to Narail Sadar Hospital morgue for an autopsy.
