Police spokesman Brigadier Jay Naicker said that the three men arrived at the house on Thursday evening, broke in, and then confronted the owner.
However, a neighbour who had witnessed the men arrive then came to the assistance of the home owner and a shoot-out ensued.
Netcare 911 spokesman Chris Botha said: “Paramedics worked fervently to stabilise the third victim and after placing him on a ventilator, they transported him to a specialised facility for the care that he required.”
However, Naicker said that the third suspect later succumbed to the wounds sustained in the gunfight.
Naicker said that the three had arrived at the house in a car that had a blue light and which had been seized during a hijacking.
