A security company employee was attacked by three men - one of whom was dressed in a paramedic's uniform similar to those worn by Netcare 911 staff.
The attack on Matthews Moremong was captured on close circuit television cameras.
Moremong was assaulted while going to check on guards posted at a minerals and metallurgy company in Randburg, Johannesburg, on Sunday.
Moremong said: "I was driving along Malibongwe Drive when a car with three white men appeared next to my car.
"The men started provoking me. They made zap signs (crossing their fingers across their necks) at me but I ignored them.
"When I got to the company I was visiting, the men pulled up next to me and two of them - the driver and the paramedic - started banging on my car.
"I opened my window to ask what was going on. The one wearing a paramedic's uniform punched me in the face.
"The other guy tried to pull the keys out of the ignition. When I asked them what I had done wrong, they said I drove badly.
"They pulled me out of the car, threw me on to the pavement and assaulted me. They kicked and punched me all over. I sustained injuries to my face and back.
"There was a female guard at the gate. She rushed off to get other guards, but by the time she came back the men had already hurt me and made off."
Moremong has reported the assault to the Randburg police.
"Luckily there were CCTV cameras at the gate and they captured the assault. I also took the car's registration numbers. I have given these to the police," he said.
Randburg police spokesman Inspector Hein van Heerden confirmed that they were investigating a case of common assault.
It has come to light that the white VW Jetta belongs to a Randfontein man and is registered under a company called Allied and Medical. Attempts to get hold of the owner proved fruitless.
Netcare 911 chief executive Wayne Grindell said: "The vehicle in question does not belong to Netcare. However, the uniform worn by one of the assailants does resemble those worn by Netcare 911 personnel.
"Unfortunately it is possible that the uniform could have been acquired dishonestly as some of our paramedics have recently fallen victim to crime. This case is most disconcerting.
"We will investigate the incident fully."
