An enthralling video showing a rare white tiger sneaking up on a zoo visitor before attempting to attack him through the glass of its enclosure has been posted online.
The 30-second clip was filmed at China's Chiemlong Safari Park last month.
A man can be seen calmly standing with his back to the animal as he poses for pictures while the big cat stalks him silently.
The tiger only pounces, with frightening speed, when the man turns around.
Luckily the glass held up to the attack and the man escaped unharmed.
