Police in Brazil are hunting a soccer referee who reportedly stabbed a player to death during a dispute over a foul call.

The fight broke out during a soccer match in the city of Barreira on Sunday afternoon when Jose Ramos da Silva, 28, protested a foul against his team. After a heated argument, the referee, identified as 26-year-old Francisco Edio Gregorio Chaves, pulled out a knife and stabbed da Silva in the chest, Momento24.com reported.

Da Silva’s brother, 24-year-old Francisco das Chagas da Silva, was stabbed four times in the back when he tried to intervene in the fight, but his injuries were not considered life-threatening.

Da Silva died at the scene before he could be treated by doctors, the Marca newspaper reported.

Police are now searching for Chaves, who fled after the attack.
