People who occupied Portland State University's library caused substantial damage to the fire alarm system.
The alarm system box was pulled out of the wall, many pull stations were activated, and fire extinguishers were sprayed throughout the building.
The Portland Fire Bureau says the in-house fire suppression system remains intact. The pull stations need to be reset and the emptied fire extinguishers will have to be replaced.
The building will be boarded up to prevent access until the repairs are made.
