Unidentified assailants have killed a madrasa student by slitting his throat in Kalai upazila of Joypurhat.

Nur Mohammad, 17, son of Mozammel Ali of Begungram village in the upazila, was a class-VI student of a local madrasa.

Nur Mohammad, who often drove a battery-run rickshaw-van to bear his educational expenses, went out of his house on Thursday afternoon with his vehicle. He did not return home since then, said Sirajul Islam, officer-in-charge of Kalai Police Station, quoting Nur's family.

Two youths hired Nur's vehicle for going to Ghaturia village from Molamgari village in the upazila, the police official added.

Locals found his body in Hazipur village yesterday morning and informed police. But Nur's rickshaw-van went missing.

Police recovered the body and sent it to Joypurhat Modern Hospital morgue for an autopsy.

The motive behind the killing could not be known immediately.

A murder case was filed.
