Founded March of 2003, the Primeiro Grupo Catarinense is a Santa Catarina based criminal group in Brazil, the largest of which in the territory.
They are allied to the Comando Vermelho and supposedly boast a membership roster of around 4,000 members within Santa Catarina. They are known to operate throughout other Brazilian states however, such as neighbouring Paraná, Mato Grosso and Mato Grosso do sol.
Similarly to many of the other gangs which plague Brazil, the PGC was founded within the Brazilian penal system, and grew to infamy for orchestrating attacks on military and police stations. As well as specifically targeting these people and their families when at home or on the street; all this in reprisal for abuses suffered at the hands of their jailers.
Subsequently, this spiraled into a tit for tat cycle of violence which saw the PGC attacking security forces, and then law enforcement in return beating their PGC aligned detainees. Which of course only spawned more and larger attacks.
Given their alliance to the Comando Vermelho, the Primeiro Grupo Catarinense is engaged in a war against the First Capital Command.
