An animal rights campaign group is offering a cash reward and free holiday to anyone who can provide information about a man who was filmed kicking a squirrel into what appears to be the Grand Canyon.
It shows two tanned men wearing boxer shorts and straw hats on the edge of the canyon. One of them appears to use snacks to tempt a a squirrel, before booting it off the edge to a certain death.
People for the Ethical Treatment of Animals (PETA) has offered a £10,000 reward and a trip to the Grand Canyon in exchange for "information leading to the arrest and conviction of the perpetrator".
The group's UK director, Mimi Bekhechi, said:
The statement also says that the perpetrator is "believed to be from a French-speaking country".
The act of cruelty was captured in a video allegedly uploaded to YouTube by an innocent bystander and not the perpetrator.
The Grand Canyon, in the US state of Arizona, is up to a mile deep and is famous for its sheer drops to the valley below.
