Incident Overview
On September 11, 2026, police were called to an educational institution on Konavonska Street in Zagreb after a student entered the building masked and attacked a classmate with a sharp object. The assailant also struck a school cleaner who intervened. Both victims were taken to KBC Sestre Milosrdnice and KBC Zagreb for treatment. Police placed the suspect under supervision and opened a criminal investigation while classes were cancelled for the remainder of the day.
Background & Prior School Violence
The attack follows a high-profile incident in December 2024 when a former student entered a Zagreb school, killed a 7-year-old girl and wounded three other children and a teacher. That case resulted in a 50-year prison sentence and prompted many Croatian schools to hire security guards to limit unauthorized access.
Official Responses
Zagreb Mayor Tomislav Tomaševic visited the scene shortly after the stabbing. The Ministry of Science, Education and Youth dispatched a crisis team to provide psychological support to students and staff. The Ministry of Health released a statement confirming that medical teams responded immediately, that the injured student required surgery for deep stab wounds, and that the cleaner sustained superficial facial injuries but remained in stable condition. Police continue to investigate the motive and circumstances of the assault.
Injuries and Medical Care
- Student victim: multiple stab wounds; surgery indicated for deep injuries; currently stable.
- Cleaner: several superficial facial wounds; undergoing diagnostic examination; vital functions stable.
Both individuals are receiving ongoing care under the Croatian health system, which has pledged full support for their recovery.
Implications for School Safety
The incident has reignited debate over security measures in Croatian schools. While guards were added after the 2024 tragedy, the masked entry of an under-age student highlights potential gaps in access control. Education officials and local authorities are reviewing protocols to balance open-school environments with the need for rapid response to violent threats.
