A father and his two daughters were found dead at their home in the capital's Kamrangirchar on Wednesday.
Police recovered the bodies of Md Babul Hossain, 40, and his daughters Mim Akhter, 9, and Jannati, 12, from the house near Rony market on Aloron School Road.
Officer-in-Charge of Kamrangirchar police station, Sheikh Mohsin Alam, said the three had committed suicide but could not ascertain why they took such a step.
He said the father and his daughters might have died from electrocution.
“Their bodies were found fastened with an electric wire, and one end of the wire was connected to an electric switch,” he said, adding that they might have taken their own lives on Tuesday night.
The policeman quoted one of Babul's neighbours as saying that Babul was a tea seller and an occasional rickshaw puller.
“Babul's wife walked out on the family two days ago, and that might be the reason for the three to kill themselves.”
The bodies were sent to the Sir Salimullah Medical College morgue for autopsy.
