Authorities eventually recaptured him after shooting him with a tranquilizer, resulting in a dramatic fall before he was safely retrieved.
Sweden saw a more tragic outcome when four chimpanzees were shot dead after escaping their enclosure and causing public panic.
Zoo officials explained that they lacked enough tranquilizer doses to sedate all the animals, forcing them to make the devastating decision to euthanize them. A fifth chimp managed to return to its enclosure on its own.
