Rapid Action Battalion (RAB) on Sunday evening detained the prime suspect of a quadruple murder who said he killed four of a family, including an 8-year-old girl, after being refused Tk200.
Sagar Ali, 27, during a primary investigation confessed to his crimes after he was detained from Brahmanbari area of Tangail's Madhupur upazila.
Major Abu Nayem Md Talat, company commander of RAB-12 confirmed the incident to Dhaka Tribune.
Quoting the detained, Major Talat said: "One of the deceased, Osman Gani, was a microlending trader. The accused Sagar Ali had failed to pay interest on his borrowed money to Gani several times."
