Andrew Oberle was talking to a tour group Thursday at the Jane Goodall Institute Chimpanzee Eden when two chimps pulled him under a security fence. He was bitten and dragged several hundred yards (meters).
The Mediclinic Nelspruit hospital said Monday that Oberle remains in intensive care.
His uncle, Carl Oberle, said his nephew had been placed in an induced coma “because he lost so much blood and his blood pressure was so low.”
