A case of attempted murder against a metro police officer who shot and wounded a motorist was dismissed by the Roodepoort Magistrate's Court on Thursday, metro police said.
Chief Superintendent Wayne Minnaar said the case was "thrown out" by the court.
"The [Johannesburg metro police]... are of the view that the officer acted in self-defence. There will be no further disciplinary steps taken against the officer."
The off-duty officer shot the motorist after he pointed a firearm at him in an apparent road rage incident.
Minnaar said the cars of the 24-year-old motorist and the officer collided at the Christiaan de Wet and John Vorster intersection in Honeydew.
The officer was with his girlfriend, a police officer, in the car.
The motorist allegedly grabbed the policewoman's firearm and pointed it at the metro police officer. The officer reached for his own firearm and shot the motorist in the leg.
Minnaar said the man was in a stable condition in hospital.
