People for the Ethical Treatment of Animals (PETA) is offering a reward of up to $15,000 for information leading to the arrest and conviction of a half-dressed man who appeared to kick a squirrel off the edge of the Grand Canyon in a video that has gone viral.

A spokeswoman for Grand Canyon National Park said Sunday that officials believe the video was shot at the natural wonder which gave Arizona its nickname, and they are working with YouTube to obtain additional information.

"If he is prosecuted and found guilty, he could spend up to six months in jail and be fined $5,000," park spokeswoman, Maureen Oltrogge, said Wednesday morning.

There are different versions of the video that was uploaded to YouTube and posted to the Daily Mail's website.

YouTube has removed the clip Republic Media linked to in its Sunday story because it violated the company's term's of service. But clips of news coverage of the incident are still available via search.

The video 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 the squirrel over the edge.

PETA wants anyone with information to contact Grand Canyon Chief Ranger Bill Wright at 928-638-7888.
