"It is serious but stable for both of them. The thing to keep in mind is that it can always change," says Nils Norling, press spokesperson for the police.
Several people were reportedly involved in the altercation, which occurred on Tuesday afternoon. The two boys, one aged 15 and the other 17, were taken to hospital. The 17-year-old has been arrested and an 18-year-old man has been detained, both on suspicion of attempted murder.
"We cannot share more details at this time," says Nils Norling.
