The latest incident at the Shaoshan Zoo in the southern city of Kaohsiung began when an orangutan pushed his way out of his cage and wandered into a nearby restaurant courtyard.
As zoo officials scurried to bring the animal under control, he gleefully overturned picnic tables and motorbikes, forcing terrified diners to cower inside the eatery.
The orang-utan was finally subdued when an official shot him in the upper body with a a stun gun.
He was then carted off for treatment in the scoop of a small bulldozer.
Incident occurred just six weeks after a 200-kilogram (440-pound) crocodile chewed the forearm off veterinarian Chang Po-yu at the same zoo.
