The Cal State Northridge campus was deemed safe after reports of a possibly armed suspect heading to the school prompted a shelter-in-place order on Friday afternoon.

Around 5 p.m., campus police determined “there is no longer a threat of a person bringing a firearm to campus.”

The campus was reopened and fully operational again.

Earlier around 3:30 p.m., a Twitter statement from school officials initially said police were “made aware of a potential subject who may be bringing a firearm to the campus.”

Anyone who was on campus was urged to “immediately leave the area.” Those who were unable to leave were advised to shelter in place.

All others were told to stay away from the area as Department of Public Safety officials responded to the scene to investigate.

Although CSUN officials note the potential threat was not verified, the urgent order appeared to be out of caution. No further details were released.
