A man has been arrested on suspicion of serious weapons offences and attempted murder after he entered a gym in Sollentuna armed.
The alarm was raised at 20.45 on Monday.
No one was injured, but the police are otherwise tight-lipped about the details of the incident.
We are of course looking into possible links to gang criminality, but it's too early to say anything more, says the police's press spokesperson Anders Bryngelsson.
