'Run Jason!': Shocking video captures heart-stopping moment boy is chased by angry bison in Yellowstone National Park



This is the terrifying moment when a young child is chased by an angry bison at Yellowstone National Park.

A holidaymaker captured the shocking footage of the boy's run-in with the 78-stone animal after it charged a group of hikers following a path through the popular park.

Giggles at the bison, which was standing close to the path built for walkers to use, turn to frantic cries as the boy runs in a circle around a fallen tree in an attempt to shake of the animal thundering behind him.

The video shows the foolhardy group, including adults and children, initially approaching the animal to take photos.

As they edge every-closer, the man behind the camera comments that the bison is tossing his head and looks angry.

While initially starting off that the bison looks 'friendly'.

He soon starts saying: 'Oh my gosh'.

Then he comments: See him gesturing? See his head movements? "II'm gonna get you"'.

But it is not until the tourists attempt to file past the animal to continue their walk, that he charges.



While older travellers manage to escape, a young boy becomes the focus of the bison's rage as he tries to sprint out of the way.

After looping around the fallen tree, the boy finally shakes off the bison, that appears to lose interest and runs off into the distance.

Fear once again turns to merriment as the relieved family laughs at the whole incident.
