Customers fled an In-N-Out Burger restaurant in Tempe, Arizona, on July 13, when a group of teenagers engaged in a violent brawl inside the dining area. The altercation occurred around 7 p.m. local time as customers were seeking shelter from an active monsoon storm.
Video footage from inside the restaurant shows several teenagers throwing punches and wrestling on the floor while other customers scrambled to exit the premises. The Tempe Police Department responded to the scene, but by the time officers arrived, the individuals involved in the fight had already left the location by foot and in vehicles.
Investigators are reviewing witness statements and speaking with restaurant staff as part of an ongoing investigation. The specific cause of the brawl has not yet been disclosed. This incident bears resemblance to a fight that occurred in May at a Chipotle restaurant in Washington, D.C., where a group of youths also engaged in a physical altercation within the establishment.
The California-based In-N-Out Burger chain has been contacted for comment.
