The police moved out to Ullevål hospital on Wednesday morning after a patient acted out and threatened employees with an iron bar.
No one was injured.
“The patient has now run away on foot, and we are searching for him.
“All our patrols are armed. No people have been injured so far,” the Oslo Police District wrote on Twitter.
The police reported the incident at 9:22 AM.
