Incident not gang-related, authorities say.

An altercation most likely driven by heat and impatience happened at Magic Mountain Sunday evening, resulting in one arrest and one minor injury.

Sheriff’s Lt. Mike Dunkle said that San Diego resident Terrence Thomas, 23, was arrested for interfering with a peace officer during the melee near the park’s new X2 ride.

“Two individuals started it, but there was a crowd of about 30 people watching,” Dunkle said. “It wasn’t gang-related, but more the frustration of standing in 100-degree heat waiting for the ride.”

Six Flags Magic Mountain security worked with sheriff’s deputies to quiet the crowd and one person was treated for a minor cut on their lip.
