National University students have demanded rescheduling the ongoing examinations in the last week of February and in the first week of March and the unconditional release of the students detained by police by Thursday.
They postponed their demonstration issuing a three-day ultimatum on Thursday.
They warned of countrywide tough agitation unless their demands are met by next Sunday.
The students of honours and post-graduate from different government colleges thronged Shahbagh in the capital on Thursday morning protesting against the postponement of their ongoing examinations under the National University.
Police detained 10 students from Shahbagh when they gathered there at around 10:30am.
The students gathered near the gate of Shahbagh police station and started protesting against the detention.
A group of police led by additional deputy commissioner (ADC) of Ramna zone police Haroon Or Rashid and Shahbagh police station officer-in-charge Mohammad Mamun Or Rashid removed the students from there. More students were seen to be detained at that time.
On the face of opposition by police, the students staged demonstration on the footpath on the opposite of the central mosque of Dhaka Unversity.
Speaking to newsmen, they alleged that they came to demonstrate with genuine demands.
They also alleged police obstructed them and detained around 30-40 of our fellow students falsely blaming them as men of Nuru (DUCSU former VP Nurul Haque) and their fellow female students have been assaulted.
One of the agitating students said, "We are not followers of any party. The detained students have to be released unconditionally. The demonstration will go on unless our demand is met."
After five minutes, the students took position at the foot of Raju Sculpture of Dhaka University where police and university proctorial team rushed and removed the students from there.
At around 1:50pm, AK Al Amin, agitating student and a 3rd year student of Sheddeswari College, talked to newsmen.
Al Amin said, "We want to finish the examinations by March. If our demands are not met, we will stage a tough agitation across the country on Sunday. Our examinations will have to start at the end of February or at the first week of March. Why cannot our examinations be taken if the ongoing examinations of seven colleges can be taken?"
About the detention of students, Shabagh police station officer-in-charge said the detained students are being interrogated.
