In a soccer match in the Brazilian state of Maranhão, a referee ejected a player from a game. The player and the ref got into an argument, and the ref pulled out a knife and stabbed the player to death. The players friends and relatives then stormed onto the field and beat the ref to death, later decapitating him and dismembering his body.
This video does not show the actual fights and mayhem on the field. Instead, it shows the aftermath at the hospital, with hospital stuff pulling the ref’s head off his body (it was not attached anyway). You can also see the results of the drawing and quartering. Hard to watch but it’s basically a medical scene in a hospital, nothing ER doctors don’t see.
