This is from the Fox Soccer blog:
An amateur soccer match turned barbaric, leading to the deaths of a match referee and player in northeastern Brazil.
The Public Safety Department of the state of Maranhao said in a statement that it started when referee Otavio da Silva expelled player Josenir Abreu from a game last weekend. The two got into a fist fight, then Silva took out a knife and stabbed Abreu, who died on his way to the hospital.
After witnessing the attack, fans invaded the field to attack the referee, who was stoned to death and quartered. Local news media are also reporting that the spectators decapitated Silva and stuck his head on a stake in the middle of the field.
In an official statement, Valter Costa, police chief of Santa Ines in Maranhão, confirmed the ongoing investigation and assured the public that suspects were being questioned.
