Three Arkansas law enforcement officers were suspended, and state police launched an investigation after a video posted on social media showed two of them beating a suspect while a third officer held him on the ground.
Authorities said the officers were responding to a report of a man making threats outside a convenience store in the small town of Mulberry, about 140 miles (220 kilometers) northwest of Little Rock, near the border with Oklahoma.
The video shows one officer punching the suspect with a clenched fist, while another can be seen hitting the man with his knee and a third holds him against the pavement.
