What Happened at Six Flags Magic Mountain?

Six Flags Magic Mountain's opening was delayed until 12:30 p.m. so responders could sweep for threats. 

"We are aware of police activity at the park and are currently monitoring the situation in coordination with local authorities," said a statement issued earlier this morning. 

However, the threat was unsubstantiated. There was no evidence of a bomb at Six Flags Magic Mountain. A spokesperson for the Los Angeles County Sheriff's Department and California Highway Patrol gave the "all clear."

In another statement issued by the amusement park, the importance of guest safety was emphasized. 

"Earlier today, the park underwent a thorough safety check by the Los Angeles County Sheriff's Department and California Highway Patrol," it read. "The park appreciates the timely response by both law enforcement agencies and values the ongoing partnership and commitment to keeping our community and guests safe."

This Comes After Another Incident Last Month

A fight involving nearly 100 guests forced the early closure of Six Flags St. Louis on its opening day.

A video of the incident shows the fight occurring near the entrance to the Eureka, Missouri, amusement park on Saturday, April 25. 

Eureka Police Chief Michael Werges told reporters that "officers responded quickly and dispersed the crowd." Most of those involved in the incident were juveniles. Six people were detained by the authorities. There were no injuries to park guests or property damage. 

While Six Flags St. Louis shares a name with Magic Mountain, the two are no longer owned by the same company. 

Six Flags merged with Cedar Fair in 2024. The company also owns Knott's Berry Farm in Buena Park, California, Cedar Point in Ohio, and Worlds of Fun in Kansas City, Missouri.

But last year, the St. Louis park was among seven properties Six Flags sold to a new owner, Enchanted Parks. Travis Kelce then partnered with Jana Partners to own 9% of Six Flags' shares. The deal was worth $200 million.
