Police in the US state of Georgia say a sheriff’s deputy has been fired after video emerged showing him pinning a black man to the floor and punching him in the face.
Roderick Walker, 26, was a passenger in a car that was pulled over by deputies for an alleged broken rear light.
After an altercation, police tried to arrest him.
Video shared on social media showed Mr Walker being held down by two white deputies, one of whom punches him.
In a statement, Clayton County Sheriff’s Office said “the deputy who repeatedly struck Roderick Walker” was to lose his job “for excessive use of force”.
A criminal investigation has been turned over to the district attorney’s office, the statement added.
The incident, which happened on Friday near the Hartsfield-Jackson Atlanta International Airport, comes amid heightened tensions in the US over racism and police brutality.
Mr Walker’s lawyer, Shean Williams, said his client had been a passenger in the lift-share car with his girlfriend, their five-month-old child and his stepson when police pulled them over.
