A police team reached the building around 12:30pm yesterday and found Shahnaz in an apartment.
She was talking to the police while standing at the door as the officers told her that her husband filed a diary mentioning that she was missing for the last three days. Then a policeman noticed that there were pieces of a dead body by the side of a bed in the living room.
Police found that the body was cut in five pieces.
Shahnaz told the cops that the body was of Sajib Hasan, 35, a transport worker, and that she had killed him that morning.
