Saso Nedeski, principal in the “St. Naum” high-school in Ohrid, said that the student who took an improvised gas pistol to school on Thursday and injured another student in the arm was considered a non-problematic child.

There was an argument during the break between two students and one of them used an improvised pistol and shot a projectile toward the other. We are talking about a very good student and I’m surprised what prompted him to do that, Nedeski told a local news site.

According to the initial reports, the student tried to shoot himself in the head after the incident, slightly injuring himself. Both students were hospitalized.
