A Brazilian businessman has been killed and three people injured in an apparent gangland assassination at São Paulo’s international airport in Guarulhos.

The victims were caught in a hail of bullets when a gunman with a rifle opened fire from inside a black car parked outside the airport’s terminal 2, which is mainly used for domestic flights.

Police identified the dead man as Antônio Vinícius Lopes Gritzbach, who had previously received death threats from the First Capital Command (PCC), Brazil’s most powerful crime syndicate.

Prosecutors reportedly describe Lopes Gritzbach as a businessman who worked with bitcoin and cryptocurrency. He had reportedly been accused of money laundering, and had recently entered into a plea bargain with local prosecutors to speak about his ties to the criminal organization, police said.
