Police said surveillance video shows a janitor pushing a garbage cart through the food court. The garbage cart rolled over and dragged a balloon, which the janitor told police he simply popped. The pieces of the balloon were recovered on the floor, said police. The police statement says there appears to be a delay of a couple of minutes between when the janitor popped the balloon and when people are seen fleeing the area. Video footage shows people in the food court visibly react to a loud sound in the area.
