A cable operator allegedly strangled his wife and six-month-old daughter over longstanding conjugal feud between the couple at Khamar Ballamjhar village in Gaibandha Sadar upazila early hours of yesterday.
The dead are Nazma Begum, 30, and Sammy. Police arrested Nazma's husband Shamiul Islam in this connection.
Quoting family members, Gaibandha Sadar Police Station Officer-in-Charge Mehdi Hasan said of Shamiul's three wives, Nazma was staying with him while two others were creating pressure on him for taking them home.
The quarrel over the issue had become an everyday affair with his wife Nazma, the OC said.
Besides, Shamiul sustained a huge loss in his business recently, Mehdi said.
The couple got locked in a quarrel on Wednesday night and at one stage Shamiul strangled Nazma and then daughter Sammy, leaving them dead on the spot, the OC added.
Local people rushed to the spot and caught Shamiul after his son Nazrul Islam, 12, raised a hue and cry for help as he tried to kill his son, the OC said, adding that on information police arrested Shamiul.
All the incident took place before Nazrul, the OC said, adding that Shamiul confessed to the crime before the police.
Police recovered the bodies yesterday morning and sent to Gaibandha Hospital for autopsy.
