The authorities of Islamic University have issued an order prohibiting the movement of outsiders on the campus without the permission of the authorities.
The decision was taken at an emergency meeting of the university on Saturday.
The university authorities have taken the decision with a view to strengthening the internal security of the university, a press release signed by IU proctor Professor M Jahangir Hossain said on Saturday night.
"IU is only open to its students. Outsiders cannot stay, roam around and carry out any activities on the campus without the permission of the proctor or relevant authorities," he said.
If they do not comply with the notice, the authorities would take steps against them.
They also asked all the construction workers to keep their identity cards, issued by the university's engineering office, with them, Jahangir Hossain added.
