Teachers and students of Jatiya Kabi Kazi Nazrul Islam University in the district held a rally and formed a human chain on the campus yesterday, demanding immediate arrest and exemplary punishment of the killers of a fellow student.

The victim is Raihan Mahmud Raj, 23, a third year student of economics department, and son of Rafiqul Islam of Char Nilaxmia village in Sadar upazila.

Vice Chancellor Mohit Ul Alam, Proctor Md Mahbub Hossain, Head of economics department Prof Nazrul Islam, and Treasurer Prof AMM Shamsur Rahman, among others, took part in the human chain.

Wearing black badges, students and teachers joined the programme.

On Sunday morning, the body of Raj, then unidentified was found in Akua bypass area under Sadar upazila, said police.

On information, police rushed to the spot, recovered the body and sent it to Mymensingh Medical College Hospital (MMCH) morgue for autopsy.

The body bore injury marks on the neck. Later, police buried him at a town's graveyard.

Criminals might have strangled the student and dumped the body in the area, said Md Kamrul Islam, officer-in-charge of Kotwali Police Station.

Family members learnt that the law enforcers recovered an unidentified body when they went to inform Kotwali police about Raj's missing.

Seeing the photograph of Raj at the police station, they identified the body as his.

Police exhumed the body on Wednesday noon and another autopsy was conducted at MMCH.

Raj was buried at his village home after the Esha prayers on Wednesday, police said.
