Here’s one more insane zombie story to add to the growing pile: a 67-year old man got into an altercation with a 28-year old on a subway in China recently over the last seat on the train, and when the younger man wouldn’t give up the fight, the elder began chewing on his arm.

This is at least the second story of so-called “cannibalism” to come out of China since June, when a woman was attacked by a bus driver who rampaged through traffic and began gnawing on her face.

Warning: the video is an eye-witness account of the fight and is extremely graphic.
