Security video showed him dumping the bleach into refrigerators and freezers in stores in Redondo Beach, Manhattan Beach and West Hollywood.

“These days, you don’t know what people are going to do. It’s ridiculous,” said one customer. “These days, you just gotta watch everything.”

In one instance, a customer and her child told a store employee that something was wrong with the ice. The child was carrying a bag of ice, which was coated in bleach, against his chest.
