The boy, 16, was attacked outside a nightclub in the Kungsholmen district by several boys of the same age. He is now under sedation and breathing with the help of a respirator.
“Doctors may carry out examinations of the boy’s brain on Sunday, to establish what injuries he has sustained,” said Anders Persson, spokesman for St Göran’s Hospital.
Five youths have been arrested on suspicion of attempted manslaughter. Police will continue going door to door on Sunday to question potential witnesses.
“We will also contact prosecutors about a request to remand them,” said Björn Engström of Stockholm Police.
