ADT security said the woman and her husband were attacked by four men in a chocolate brown Audi A3, previously seen at the couple’s gate this week.
ADT Pretoria district manager Leon Muller said: “We suspect the couple had been followed home from the shops.”
Muller said fortunately ADT had a patrol vehicle dedicated to the area and a reaction officer who witnessed the attack was immediately able to assist the couple and call for medical assistance.
Netcare 911 arrived on the scene and spokesperson Athlenda Mathe said the couple sustained moderate injuries and were stabilised before they were taken to hospital.
The attackers are still at large but ADT is working closely with the police on a lead, said Muller.
