Authorities in Maryland say two women threw bleach and another chemical on each other during a fight at a Walmart, prompting officials to evacuate the store for two hours and call in a hazardous materials team.
Fire officials say 19 people had to be taken to hospitals, although only one was thought to have serious injuries. That person was taken to the Wilmer Eye Institute with a potentially serious eye injury.
Fire officials were called to the store in the Baltimore suburb of Arbutus shortly before 11 a.m. Saturday.
Fire Department spokesman Glenn Blackwell says one person was arrested and charges are pending.
