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 village Saratala of Narail Sadar upazila.

Police and local people said that Rony got married to Achhiya around four years back with consent of their families but later he maintained extramarital relationships with other girls.

The couple used to lock into arguments 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 couple had a minor son who was out of the house during the incident.

Mahmudul Rahman, officer-in-charge of Narail Sadar police station, said that he suspected that Rony, in a planned way, killed his wife over his extra marital relationships.

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 post-mortem examinations.
