Sweden's schools inspectorate ordered the temporary closure of the prestigious boarding school in Värmland on Wednesday after two boys were burned with electric irons in another case of ritualistic bullying. The inspectorate said the school would be closed from Thursday for up to six months.
The school has been under fire in recent years for its inadequate response to several reported cases of bullying.
Lundsberg was founded in 1896 and is one of three elite fee paying schools in Sweden. It has about 200 boys and girls of secondary and upper secondary school age.
All pupils were picked up by their parents on Wednesday.
School board member, Ulf Rehnmark, told SVT that the closure was a drastic measure and would harm the pupils.
"It is a very drastic decision to close a school which has 170 pupils who live there. There will be huge problems for these young people. We have an understanding of what the Schools Inspectorate concluded. But we think it is the wrong way to go, with an immediate shutdown."
