"This was not a 'prank,' nor will it be treated like one," the district said. Author: Adrianne M Haney Updated: 11:57 PM EST February 24, 2021 COBB COUNTY, Ga. — A "code red" alert that sent classrooms across the Cobb County School district into lockdown earlier this month later turned out to be a false alarm. But now, the school system says police have evidence that someone was able to get into the emergency alert system and purposely activate the false alarm. The district's emergency alert system, AlertPoint, sent principals and employees an alarm message that immediately prompted all campuses into "lockdown" status.
