Chittagong: A faction of Bangladesh Chhatra League (BCL) vandalised the academic building of Chittagong University and the vice-chancellor's office on Tuesday demanding suspension of a university teacher.

The unruly BCL leaders and activists also ransacked two private cars, several motorbikes and 20 flower vases in front of the offices of the VC and registrar and assaulted CU correspondent of TV channel Banglavision Shahjahan Khan while taking the footage of the vandalism.

Earlier, the BCL group, led by CU unit President Alamgir Tipu, gave a 24-hour ultimatum to the university authorities to suspend Md Amir Uddin, an associate professor of the university's Institute of Education Research, as he is leading a movement against holding tax in the city.

They went on the rampage as their demand was not fulfilled within the deadline.

The BCL men, loyal to Chittagong City Corporation (CCC) Mayor AJM Nasir Uddin, alleged that Amir, general secretary of Chattagram Kordata Surokkha Parishad, is plotting a conspiracy against the elected representatives through social media.

They had also allegedly threatened Amir at gunpoint at his office to keep him away from the movement.

The Parishad launched the movement demanding that the holding tax on landlords which was increased by CCC last year be revaluated.

Athazari Police Station Officer-in-charge Belal Uddin Jahangir told news agency UNB that additional force has been deployed on the campus and the situation was now under control.
