Dhaka, Sept. 22 -- The allegation surfaced as protests continued for the fourth day on Sunday at the Bangabandhu Sheikh Mujibur Rahman Science and Technology University or BSMRSTU.

The protesters alleged the teachers asked the students to stop demonstration or else the teachers will hold back the students' certificates.

The teachers also threatened the students to "wait until resumption of classes and exams", according to the protesters.

VC Nasiruddin, however, has denied the allegation that teachers loyal to him threatened the protesters.

"There is no scope for this," he told bdnews24.com.

He also said the authorities were trying to find a peaceful solution to the problem.
