"Apparently the chopper crashed into the overbhead power cables."
Africa confirmed that there were no fatalities but added that eight occupants had been injured in the accident.
ER24 spokesperson Russel Meiring confirmed this, saying one had sustained serious injuries while seven others had sustained minor to moderate injuries.
"Paramedics treated the patients and provided the seriously injured with advanced life support interventions before they were transported to a nearby hospital for further treatment," Meiring said.
Roads near the accident will reportedly be shut for hours because of aviation fuel on the road surface.
