A group of children discovered the body of a seven-year-old girl in Reiger Park in Boksburg, on the East Rand.
The children alerted adults and ER24 paramedics were called to the scene.
"ER24 paramedics arrived on the scene to find bystanders performing CPR on the young girl. Paramedics immediately took over CPR and immediately initiated advanced life support interventions," ER24 spokesperson Russel Meiring said.
Unfortunately, nothing could be done for the girl and she was declared dead at the scene.
Meiring said that the cause of death is still unknown. Police are currently investigating the matter.
