Netcare 911 paramedics, its rescue unit and other services responded to an accident on the N1 north bound just before William Nicol Drive in Randburg late this afternoon.
Upon their arrival on scene they found that two vehicles were involved in a rear-end collision. One person was found to be in a serious condition and another person was found to be in a critical condition and entrapped in the vehicle.
Services had to make use of the Jaws of Life to extricate the critically injured patient from the vehicle.
The Netcare1 helicopter was activated to airlift the critically injured patient to hospital and the second patient was transported to hospital for further medical care required.
Exact detail to the cause of the accident and preceding events will remain the subject of a police investigation.
