(AZ Central) Officials believe a video that appears to show a man kicking a squirrel off a cliff was shot at the Grand Canyon, a park spokeswoman said.
"The rangers do believe it is at Grand Canyon in the national park," said Grand Canyon National Park spokeswoman Kirby-Lynn Shedlowski. "It is under investigation. We are working with YouTube to see if we can get any additional information."
There are different versions of the video that was uploaded to YouTube and posted to the Daily Mail's website. It shows two shirtless men standing on a cliff.
One scene shows a man shooting video while another man dressed in black shorts lays a trail of food to the edge.
Another scene shows the man in black shorts putting on his shoe. A squirrel follows the trail of food to the edge.
In another scene, the man in black shorts appears to kick it over the edge.
Shedlowski could not say whether the man could be arrested for animal cruelty or face other criminal charges.
"They (investigators) would have to be able to identify the individual which is going to be problematic," she said.
