“It feels ok now, but it was a bit unpleasant,” the principal Martin Erberth told local paper Skånskan.
According to the paper, the student got annoyed after he couldn’t get one of the school computers to work and started to throw furniture around, lobbing billiard balls out of the windows.
He also walked around school premises smoking cigarettes and refusing to stop, despite being told to do so by staff.
When the boy’s teachers couldn’t stop him from acting up, the principal was called in.
However, the boy then became even more aggressive, kicking at them and taking a stranglehold on the surprised Erberth, according to the paper.
Finally, police officers managed to overpower the boy, whom they think was under the influence of drugs, and take him down to the station.
The boy is now under suspicion of threatening behaviour, damaging public property and narcotics crimes.
The boy also filed a separate report against the school after the incident, according to the paper.
