At Islamic University (IU), leaders and activists of the banned Chhatra League carried out a poster campaign late at night. The incident occurred on Tuesday night, and photos and videos of the activity spread across social media, showing posters and banners being placed at several campus locations including the administration building, Jhal Chattar, Rabindra-Nazrul Arts Building, central library, and the Science Faculty gate. However, by morning, most of the posters were no longer visible on campus.

The incident sparked anger among leaders of active student organizations at IU. Leaders from groups such as Chhatra Shakti, Islami Chhatra Andolon, and Chhatra Dal condemned the act, accusing the banned group of returning to campus activities and recalling past violence. They demanded accountability from the university administration for allowing the incident to occur.

IU Proctor Professor Dr. Shahinuzzaman stated that security forces were deployed immediately after the incident around 3 a.m. and that the situation was brought under control. He added that CCTV footage was being reviewed to determine how the individuals entered the campus and that the matter had been handed over to the IU police station.
