Tensions escalated at a middle school in Kypseli, Athens, following a recent knife attack that left a 14-year-old student injured. The incident has sparked fear and concern among students, teachers, and parents.

On the morning of December 17, 2025, students returned to school to find the doors open after a previous lockdown had ended. However, they quickly staged a new protest, placing locks on the doors and trapping two school administrators inside. The action was reportedly a response to the continued presence of the 16-year-old who had attacked her classmate.

According to local reports, the administrators repeatedly asked the students to unlock the doors, but the protest continued until police arrived to remove the locks and restore access.

Outside the school, students and teachers remained gathered, waiting for official guidance on how the situation will be resolved and when normal school activities can resume. In the midst of the tension, the mother of the 16-year-old involved emphasized her desire to support her daughter without labeling her a criminal, highlighting the broader concerns of families affected by the incident.
