PHILADELPHIA (AP) — Philadelphia police are seeking a mob of people, mostly teens, who looted a pharmacy. Police on Tuesday released video that shows about 60 people flooding into a Walgreens on South Street around 10 p.m. on July Fourth. Some are shown knocking items off shelves while others are shown fleeing with merchandise. Police Capt. Sekou Kinebrew tells WPVI-TV a cashier who tried to intervene was hit on the head with a glass bottle.
