PIEDRAS NEGRAS, Coahuila – Authorities in this border city are investigating a disturbing video widely shared on social media where a man is seen stabbing a dog. The footage sparked outrage with many residents calling for an arrest.

The video surfaced over the weekend as angry residents took to social media, looking to identify the man seen walking up to a dog, luring it close and then violently stabbing it with a large knife. The defenseless dog can be seen shaking as it bleeds out and eventually dies, while the man walks back to a table and drinks a beer. Piedras Negras is immediately south of Eagle Pass, Texas.
