RIO DE JANEIRO (AP) — A Black man died after being beaten by supermarket security guards in the Brazilian city of Porto Alegre on the eve of Friday’s Black Consciousness Day observations, sparking outrage after videos of the incident circulated on social media. A short clip showed one guard restraining Jo„o Alberto Silveira Freitas just outside the doors of a Carrefour supermarket while the other pummeled him with repeated blows to the face.

Dozens of protesters entered a Carrefour in Brazil’s capital, Brasilia, on Friday morning, chanting “Black lives matter!” One held a sign reading: “Don’t shop at Carrefour. You could die.” Inside another Carrefour in Rio de Janeiro, protesters shouted “Carrefour Killer!” as a black man lay still atop the conveyor belt of a checkout. They forced the store’s closure
