The incident is said to have occurred on Sunday at a residence adjacent to the school, according to the police. The crime classification is assault, but no one has been formally suspected at present.
According to Expressen, a notification has been sent to guardians, students, and staff that older students are alleged to have subjected younger students to "both psychological and physical abuse".
Five students have been expelled from the boarding school, according to principal Lars Jonsson.
The students are not expelled from school, but from the boarding school, from the dormitory. They have signed a residence contract and if you do not comply with it, you can be expelled. It is not the police who decide, but our disciplinary board, he told Expressen.
According to the police, the incident involves multiple victims and multiple suspects, all of whom are under the age of 18 but over 15.
The boarding school Lundsberg has students from ninth grade to high school graduation.
