The drama unfolded in the early hours of Sunday morning, when the man in his twenties, was driving in a car with some friends.
According to a statement from ER24 bystanders reported that the man was on the roof, screaming that someone was chasing him even though there were apparently no visible signs of anyone close by.
"ER24 paramedics and other rescue services arrived on scene and tried to get the man to come down to safety. When authorities took out flashlights in order to see better, the man allegedly believed that they were fire arms and then jumped off the building. He landed in a empty parking lot and sustained serious injuries including various fractures," said ER24 spokesperson Pieter Rossouw.
