Video footage shows law-enforcement officers in Woodson Terrace, Missouri, setting a police dog on a Black man while he was being arrested, and watching as the dog bit him and he cried out in pain.
The video, filmed by a bystander, shows the officers arresting the man on Monday, and leaning him over the hood of a car while another officer stands nearby with the dog.
The officer then lets the dog reach the man, and it bites him as the man grabs his ankles and says "help," but the officers do not intervene.
