Duja finalised the decision at an urgent general meeting on Wednesday night.

As part of the agitation, Duja will form a human chain in front of Aparejeyo Bangla at 11:00am tomorrow and submit a memorandum to the Vice Chancellor on Sunday demanding permanent expulsion of the culprits from the university.

Since police failed to arrest any of the attackers even a week after filing of the case, Duja will lay siege to the Ministry of Home Affairs on Monday.

Prominent journalists, teachers, writers, intellectuals, cultural activists and students will hold a rally at Aparejeyo Bangla on Wednesday to express solidarity with Duja.

At the meeting, members of the organisation expressed grave concern over the failure of the DU authorities and the police to take any actions against the Bangladesh Chhatra League (BCL) activists.

Duja filed a case against 12 BCL activists on September 17 for attempting on the lives of journalists and carrying illegal arms. Later, four small bombs were exploded in front of Modhur canteen and Duja office at TSC on September 18 and 19.

Duja president and general secretary is repetitively receiving threats over mobile phone to withdraw the case.

Earlier, DU authorities expelled four BCL activists temporarily for their involvement in the attack on journalists.

Meanwhile, Jatiyatabadi Chhatra Dal (JCD), student wing of the ruling BNP, yesterday demanded immediate arrest and punishment of the BCL leaders who beat up the journalists and blasted several crackers in the last few days on DU campus.

In a statement JCD DU unit President Hasan Mamun and General Secretary Saiful Islam Firoz also demanded immediate expulsion of the culprits from the university.

While talking to The Daily Star, Firoz said if BCL wants to damage the congenial atmosphere of the campus, JCD along with general students would declare BCL unwanted on the campus.
