The crew was responding to an emergency at the Happy Valley informal settlement early yesterday morning.
It is the latest of several attacks on medical personnel in the city in recent weeks.
The paramedics were ambushed by four armed men as they were loading a patient into an ambulance.
Emergency medical services’ Robert Daniels says an official was stabbed and the vehicle vandalised.
"The attackers demanded the crew’s personal valuables including wallets, mobile phones and handbags and afterwards they stabbed the paramedic with a broken bottle. The other paramedic was threatened with a knife but fortunately not harmed."
