Four members of a family suffered burn injuries as criminals set fire to a house at Lochonpur village in Narsingdi's Raipura upazila early yesterday.
On suspicion, police have arrested two men -- Kajol Mia, 30, and Robin Ahmed, 28 -- from the same village yesterday afternoon.
The family members alleged that their neighbours, with whom they had a land dispute, committed the arson. Raipur police said the allegations would be looked into.
All four victims – Muktamoni, 16, Sweety Akter, 13, Preety Akter, 11, and Khatun Nesa, 60 -- are being treated at the Burn and Plastic Surgery Unit of Dhaka Medical College Hospital (DMCH).
Muktamoni, Sweety, and Preety are the daughters of Shamsul Mia, while Khatun Nesa is their paternal aunt.
Ratna Akter, elder sister of the girls, said they had a long-running dispute over a piece of land with their neighbours. She said she suspected that the crime was committed by them.
When contacted, Mohsinul Kabir, officer-in-charge of Raipura Police Station, said there were back-to-back murders in the area a few years ago, in which brothers of the girls -- Sohag and Biplob -- were the accused and on the run.
“We are trying to find out whether this incident is connected to the murders or whether it was done by someone else,” he added.
