California State University Northridge police told students in the parking lot to leave, and others on campus to shelter in place, after a man was reported to have a gun in his car Monday morning.
By nearly 9 a.m., police gave the all clear after the report was determined to be unfounded, and there was no threat.
"The report of an individual with a gun on campus was determined to be unfounded. No threat has been identified on or around campus. The campus is open and operational," police said.

"If you are in a campus parking lot – leave now. If you are on campus, please shelter in place. All others are advised to stay away from campus until further notice," the tweet from Cal State Northridge read.
