Sylhet Shahjalal University of Science and Technology (Sust) today suspended four BCL activists for their alleged involvement in Sunday's attack on agitating teachers.

Aminul Haque Bhuiyan, vice-chancellor of the university, said the proctorial body has taken action after it found their involvement in the attack.

The VC told our Moulvibazar correspondent that they got the evidence after verifying video footage on the incident. 

The four BCL activists are: Dhani Ram Roy, Abdullah Al Mamun and Jahid Hossain Nayeem, students of statistics, political studies and forest departments respectively.

On Sunday, alleged Bangladesh Chhatra League activists swooped on teachers during the latter's pre-scheduled demonstration to stop VC Aminul Haque Bhuiyan from entering his office.

Several teachers, including Prof Yasmeen Haque, wife of noted writer Prof Muhammed Zafar Iqbal, were assaulted at that time.

The incident triggered a firestorm of protest in the social media with condemnations from different political parties and socio-cultural organisations continuing to pour in.

A three-member probe committee was formed on Sunday night to investigate the incident.

The teachers, who have been demonstrating for the removal of the university's vice-chancellor since April 12, observed work abstention yesterday.

Meanwhile, the BCL last night suspended three of its Sust unit leaders -- Abu Saeed Akond, senior vice-president, Anjan Ray, vice-president and Sajedul Islam sabuj, joint general secretary -- in connection with Sunday's incident.
