Students who led the agitation on the day were recorded in video cameras of the university and they would be punished on completion of the probe, said university Proctor Prof Shamsul Alam.

Acting Vice Chancellor Prof KHM Shahadat Hossain Mondol told The Daily Star that the punitive measures include cancellation of studentship and cautioning students' guardians.

The day-long campus violence ensued following intrusion of three unidentified youths into a women's dormitory on October 29 night.

The university authorities filed two cases against 54 students and 400 unidentified students.

Prof Mondol, also convenor of a seven-member committee formed to investigate the incident expressed his belief that some student leaders of left leaning parties and a section of teachers might be involved in the 'pre-planned incident'.

Meanwhile, different students bodies, teachers and social workers continued their agitation on the day blaming the university authorities for violence and demanded removal of VC and proctors and immediate release of the arrested 54 students.
