On Saturday evening July 07, 2018 a fight in the Ontario Mills Mall food court sent a massive law enforcement response as some shoppers mistook the fight for an active shooter situation. According to Police, one person involved used a Taser during the scuffle. The sound of the Taser scared shoppers who thought a shooting happened and panicked. In the panic to flee the scene, one person was injured, possibly suffered a broken leg, after being trampled by the crowd. The mall was evacuated as a precaution as Police conducted a store by store search of the mall for the people involved in the fight. The fight remains under investigation.
