The mayor of Phoenix apologised on June 16 after videos emerged showing police in the southwestern US city violently arresting a family with young children.
The videos, shot when the arrest happened last month, show police using foul language while shouting at the family to get out of their car, and threatening to shoot them.
A woman later emerges from the vehicle with two young children. She hands them over to a bystander before being arrested.
Separately, an officer is shown kicking the legs of another man who he is handcuffing against a police car.
“I, like many others, am sick over what I have seen in the video depicting Phoenix police interacting with a family and young children,” Mayor Kate Gallego wrote in a statement posted on Twitter.
