A man banging his skateboard on the floor of a food court in a Dallas mall set off a frenzied evacuation and reports of an active shooter in the area. Videos posted to social media around midday Monday show a panicked crowd running for the exits of the NorthPark Center mall. Police Chief Eddie Garcìa told The Dallas Morning News that the “mentally disturbed” man “made hand gestures mimicking a shooting” when police arrived, though he was unarmed. No one was injured, but one person reported chest pains.
