The expelled activists are Shahid Uddin, Zulfiqar Ali, Mizanur Rahman Sohag and Monirul Islam, said a JCD press release.

The DU unit of JCD also served showcause notices on President of Zahurul Haq Hall unit of JCD Tanjilur Rahman and Organising Secretary Shoeb Khandakar Shoeb, asking them to explain within three days why they should not be relieved of their positions for failing to prevent the attack on Tusher.

The two men will face disciplinary actions if the allegation of their involvement in the attack is proved, the press release said.

JCD's DU unit President Amirul Islam Khan Alim and General Secretary Hasan Mamun approved the decisions.

While giving their reaction to the expulsion of the four JCD activists, some members of the Dhaka University Journalists' Association (DUJA) however expressed their dissatisfaction with the mere showcause notice on Tanjilur Rahman. They said it was Tanjilur who ordered the attack on Tusher and therefore he should have received a stern punishment.
