I don’t know anything about this accident but it looks like it could be from Indonesia, or elsewhere in South East Asia. I think I’ve heard the screaming voice say Allahu a few times.
A man, presumably a motorcyclist had his leg and penis ripped off at the hip. He’s lost a lot of blood – you can see a pool of it around him – and is clearly in distress, although I don’t think it’s him singing Allahu. Large number of people that gathered round to see the spectacle support my guess that this could be from Indonesia cause the country is ridiculously overpopulated so you’re never too far from large crowds of incompetent tools. Lots of flip flops there too.
