Campbell High School in Smyrna, Georgia, was placed under a “code red” lockdown on Monday.
At least two people have already been taken into custody. Police say that a threat was called in via walkie-talkie, but are not releasing any further details at this time. It is not known if the suspect was a student. The lockdown has now been listed.
One student tweeted out saying that they saw a police officer come into a classroom with a drawn weapon during the event.
