A zookeeper dressed up as a white tiger to prepare staff on how to deal with a real one escaping.
The man in the costume crawled around the floor while wearing a white hoodie and tiger face mask.
He could be seen prowling around on his hands and knees as the animal keepers slowly honed in on him.
They could also be seen wearing green suits, and helmets and grabbing nets in preparation to capture the pretend tiger.

The fake big cat then ran towards them before a keeper acted out a tranquillisation on him.
He fell to the floor and zookeepers wrapped him in netting, before picking him up and carrying him onto the back of a truck.
Zoo chief Masaru Kaminaga told local news that the annual drills are an important training exercise.
He said: “In the event of an emergency, it is important for each person to understand their role and respond accordingly.”
The Tobu Zoo, located in Miyashiro Town, Japan, holds the annual training drill every year.
