Police recovered the body of the victim, Nazmun Nahar Nila, 36, wife of Jahangir Alam, in the afternoon.

The victim's son, Niloy, a student of class six, found her mother lying unconscious on the floor of their flat at 1:30pm.

As Nila did not reply to Niloy's call, he informed his aunt about the matter over cellphone. Neighbours thronged the spot and found her dead. They informed the police immediately.

The family members told the police that Nila was alone during the incident as her two sons left for school at 8:00am while her husband stays in Gazipur and visits home twice a week.

Police said primary probe suggests that some known person aided by more people have committed the crime.

Police suspect the housewife was killed after being raped as scratches were found on her neck and nothing was taken away from the house.
