Unidentified miscreant have stabbed a woman and her two daughters to death at Boubazar area of Narayanganj's Shiddirganj.
The deceased are Nasrin Begum,28, Nusrat,6 and Khadiza, 2.
"Nasrin and her daughters were found dead this morning at their home. We suspect they have been murdered over family dispute," said Sazzad Roman, Narayanganj police's special branch inspector.
Another girl was also stabbed at that time. She was later admitted to Dhaka Medical College Hospital in critical situation.
The police have kept the spot cordoned off to collect evidence and the bodies will be sent to morgue later for autopsy.
