Six Flags Entertainment reopened Six Flags Magic Mountain on Monday afternoon, May 11, after law enforcement officials cleared the park following a bomb threat that delayed operations for several hours. Authorities told ABC 7 that the threat came in around 7:45 a.m., roughly three hours before the Southern California amusement park was scheduled to open to the public. The call prompted a large emergency response involving the Los Angeles County Sheriff's Department, the California Highway Patrol, and local firefighters, who conducted a sweep of the sprawling Valencia property before ultimately determining there was no active danger.
