Two sisters were found hanging from an iron rod on the terrace of their house in the Majumdari area of Sylhet city on Tuesday.
The deceased were identified as Rani Jamidar (33) and Fatema Begum (27), daughters of Kalim Ullah. Police suspect they committed suicide over a family feud.
The couple's other daughter relocated to the UK after her marriage.
Around 6am, neighbours found the bodies of the two sisters hanging from the iron rod on the terrace of the house and informed the cops.
A team from the local police station rushed to the spot and sent the bodies to the local hospital morgue for post-mortem.
"A probe has been ordered into the deaths," the officer said.
