It looks to me like the video is from an Asian country. It shows a man being attacked by a fairly large dog. A few men come to his aid.
Different angle of pit bull mauling of a thief who broke into a house in Cape Town, South Africa. The original video is HERE. This angle is not as good as the other one, plus this video is very shakey.
Two pit bulls attacked a thief when he entered the property at Lotus Riven in Cape Town, South Africa. Western Cape police confirmed the 37 year old man was admitted to hospital, where he died.
