This happened somewhere in Brazil. The guy apparently robbed the wrong person in the wrong place, and got his due punishment.
The video shows the alleged thief getting whipped by multiple men with what looks like twigs. The punishers turned his back black, and some appeared to do the CV sign at the end of the video. Comando Vermelho is one of the biggest street gangs in Brazil.
Props to Best Gore member @void33 for the video:
