A three-wheeler driver in Sirajganj was stabbed to death on Sunday (Nov 18).
The victim has been identified as 20-year-old Munir, whose body was found near a rail line in Kalia Haripur village of the Sadar Upazila.
Sadar police Inspector (investigation) Rafiqul Islam said that Munir still had his mobile and cash on him when he died which rules out robbery.
His body bore signs of assault and a family feud might be the motive behind the murder, he added.
