The alarm came to the police at 12.20 due to a quarrel between several students in a room inside the school, which has students from preschool to ninth grade.
When the police arrived at the school, the room where they had been arguing was blocked.
- A boy in the age of 15 must have received stab or cut injuries and was taken to hospital by ambulance, says Jimmy Modin.
The room is cordoned off pending a technical investigation and the incident is initially classified as attempted murder.
Witnesses at the school are said to have seen the incident and now the police are there and talking to them on Monday afternoon.
- The perpetrator is not left at the school, but we are now looking for a person, but who is not suspected of anything yet, says police spokesman Jimmy Modin.
