Police primarily suspect that Jagannath University (JnU) student and online activist Nazimuddin Samad was murdered due to previous enmity as no anti-religious writing was found after the scrutiny of his Facebook status.
Police have also kept 5-6 suspects under close watch in connection with the killing that triggered uproar among the student community.
A group of assailants, numbering 4-5, swooped on Nazimuddin Samad at Ikrampur of Sutrapur in the capital on Wednesday night, and hacked and shot him indiscriminately, leaving him dead on the spot.
Sub-inspector of Sutrapur Police Station Nurul Islam filed a case in this connection on Thursday night accusing 4-5 unidentified miscreants of the murder.
Inspector (Investigation) of the police station Samir Kumar Sutradhar was made the Investigation Officer (IO) of the case.
“After preliminary investigation, it seems to me that the killing took place due to previous enmity as no anti-religious comment was found in his Facebook status,” the IO told UNB on Friday evening.
“Anyway, the possibility of the involvement of a religious extremist group is also there in our mind,” the IO said.
Replying to a question, he said Nazimuddin came to Dhaka barely two months back.
“We’re trying to ascertain whether he had any previous enmity in his area in Sylhet,” he said alleging that his relatives who came to
Dhaka to bring his body from Sylhet did not give any information in this regard.
However, the investigators are keeping a close watch on 4-5 suspects who were vary close to him, inspector Sutradhar added.
Meanwhile, Nazimuddin Samad was buried at his family graveyard at Tukabharaut village, Bianibazar in Sylhet on Friday morning. The burial took place around 11am after a namaz-e-janaza at the village.
Nazimuddin Samad, 26, an LLM student of JnU, was also the information and research secretary of Sylhet unit of Bangabandhu Jatiya Jubo Parishad and an activist of Sylhet Ganajagaran Manch.
