A woman and her two minor children were found dead with their throats slit at her house in Babla village under the district's Belabo upazila.
The deceased are-- Rahima Begum,36, her son Rabbi Sheikh,12, and daughter Rakiba Sheikh,7.
Safayet Hossain, Officer-in-Charge of Belabo police station, confirmed the matter.
Locals said Rahima used to live with her two children in the house as her husband works as a painter in Kishoreganj.
As no one came out of their house for a long time on Sunday morning they started knocking the door.
Getting no response, they broke the fence of their house and found their bodies lying on the floor.
Rahima’s husband Gias Uddin Sheikh suspected they were killed following previous enmity over a land.
