The alarm was raised at the school in Trollhatten, an industrial town 75 kilometres north of Gothenburg.
The black-clad suspect appears to have posed for photographs with pupils before embarking on his murderous rampage.
“We thought it was a joke, a Halloween prank or something, but it wasn’t,” said one girl. “Lots of pupils started to cry when the teachers and the other pupils were injured.”
The search for a motive
Police have not given any details of a possible motive for the attack.
The attacker’s social media sites have been examined and suggest an interest in neo-Nazi ideology and memorabilia, it has been claimed.
