According to the backinfo I got, this happened in Manaus, state of Amazonas, Brazil. The video shows local twinks delivering beating to an alleged thief.
Armed with clubs, the mob initially wanted the thief to lay his hands on the step next to him, so they can beat them to a pulp. But the accused thief instinctively retracted his hands, which prompted the mob to unleash the clubbing on any part of his body they could land.
At around 0:17, somebody lands a blow square on top of his head, knocking him the fuck out, and judging by how tensely he bent his wrist, causing damage to the brain. He remained unconscious for a bit, but whereas the mob resumed the clubbing, the pain eventually made him come to.
The mob kept pulverizing his knees and arms, and only stopped when one of them hit and broke the water pipe to the house. I think this guy will be a vegetable for a bit, if not the rest of his life.
Props to Best Gore member @natural-selection-2 for the video:
