A police officer grabbed a disabled man by the shirt and appeared to wrestle him to the ground in a popular holiday resort town.
Shocking video footage shows the man ending up on the floor where the policeman, still holding onto his top, and his colleague struggle to pull him back to his feet.
The man, who has the use of only one leg, ends up sprawled in the road.
The confrontation between the cop and Alroy Kerspey, 46, was caught on camera by his wife Mercia, 39, who was a passenger in the car.
They had been driving on a road where they have a shop in the coastal town of Knysna in southern South Africa's Western Cape province when police pulled them over.
