Intelligence SA shared a video of a road rage incident which occurred on London Road near Alexander in Joburg.
In the video an angry man is seen vandalising a Range Rover and beating up its driver.
Intelligence Bureau SA said on its Facebook page that the two vehicles had a minor bumper bash.
"So the elderly man (71) in the Range Rover pulled over so they could exchange details but the man in the other vehicle, a Porsche, went ballistic and acted totally irrational and started attacking the elderly man in the vehicle," Intelligence Bureau SA wrote.
