The Greek police, known as ELAS, conducted a midnight operation at Aristotle University of Thessaloniki (AUTH) that resulted in the arrest of 38 individuals. The arrests occurred after a public film screening that took place in the university's faculties, during which some attendees lingered in the area beyond the event's conclusion. This prompted authorities to intervene and enforce the recent policy established by the university's management aiming to prevent any further disturbances in light of previous incidents on campus.

Prior to the midnight intervention, the university had been under scrutiny following several unrest episodes, prompting the rectorate to prohibit all events on campus in an effort to maintain order and ensure operational continuity at the institution. This decision appears to reflect broader concerns about safety and control within university environments, which have been increasingly challenged by protests and student activism in Greece.

Initially, law enforcement authorities carried out 48 detentions during the operation, but 38 individuals were subsequently arrested following their investigation. A significant show of force was deployed, involving various police units, including riot police and special intervention units, to manage the situation and address the public safety concerns surrounding the university's activities.
