WION:  The killing, which has sparked protests across Brazil, occurred late on Thursday when a store employee called security after the man threatened to attack her, cable news channel GloboNews said, citing the Rio Grande do Sul state military police.  Amateur footage of the fatal beating and tributes to the Black victim were published on social media. He was identified in local media by his father as 40-year-old Joao Alberto Silveira Freitas.
 News website G1 later reported that an initial analysis by the state forensics institute indicated the cause of death could be asphyxiation.  In a statement on Friday, the local unit of France’s Carrefour SA said it deeply regretted what it called a brutal death and said it immediately took steps to ensure those responsible were legally punished.
 It said it would terminate the contract with the security firm, fire the employee in charge of the store at the time of the incident, and close the store as a mark of respect.
In Porto Alegre, protesters on Friday afternoon handed out stickers depicting the Carrefour logo stained with blood and called for a boycott of the chain. They held up a banner in Portuguese reading “Black Lives Matter” and signs calling for justice for Beto, a nickname for the victim.
