The student, whose identity was not reported, was attacked by nine other students during a hazing ritual Saturday at the prestigious boarding school Lundsberg, The Local.se reported.
The Swedish Schools Inspectorate said the attackers used an iron to burn the victim, whose injuries were described as minor.
Lundsberg, which was founded in 1896 and is the alma mater of Prince Carl Philip, has a history of students assaulting others in hazing rituals. In May 2012, several students at the school spoke out after being forced to perform oral sex and eat manure.
In October, the school was told by the Swedish Schools Inspectorate that it would face a $75,000 fine if it didn't act to curb bullying and violence among students.
