On Saturday afternoon, Agrani Bank's Haripur Gas Field Branch's officer Moudud Ahmed hired a CNG-run auto-rickshaw from Haripur area of Sylhet's Jaintiapur upazila to go to Bandarbazar in the city.
Upon reaching there around 7:45pm, he locked into an altercation with the driver over fare. He was then beaten badly by the driver and his transport worker associates, said witnesses.
Moudud (35) died at Sylhet MAG Osmani Medical College Hospital that night, hour after he was taken there by locals.
His brother filed a case with Kotwali Police Station on Sunday. But two days after the murder, police are yet to arrest any accused.
Moudud, hailed from Mymensingh's Gouripur upazila, used to work as an officer (cash) at the bank and lived in a rented house at Haripur.
In the case filed by his brother Abdul Wadud, auto-rickshaw driver Noman Hasnur of Tukerbazar Paschimpara of Sylhet upazila is the only named accused. Several other unnamed persons are also indicted.
SM Abu Farhad, officer-in-charge of Kotwali Police Station, said, "With the help of technology, we were able to confirm the identity of the prime accused and the case was filed against him along with others. But we couldn't arrest him yet as he is on the run."
"We're trying to track all the accused," the OC added.
