The military police in Rio Grande do Sul state said the man had threatened a female worker at the supermarket, who called security.
In 2018, a security guard at a Carrefour in Sao Paulo state beat a stray dog to death with a metal bar.
Protests broke out across Brazil on Friday, the country's Black Consciousness Day, after a video went viral online showing a black man beaten to death by white security guards at a supermarket in the southern city of Porto Alegre on Thursday night.

Supervisor Adriana Alves Dutra had the authority to stop the guards from beating 40-year-old Joao Alberto Silveira Freitas on November 19, said homicide investigator Vanessa Pitrez with the Civilian Police.
News website G1 later reported that an initial analysis by the state forensics institute indicated the cause of death could be asphyxiation.
The supermarket chain announced it would end its contract with the security firm, suspend the store manager and temporarily close the supermarket branch.
A Reuters photographer saw Black city council members protesting outside the supermarket, and a larger anti-racism demonstration was planned there for later on Friday, a Black Consciousness holiday in several cities across Brazil.

"But these measures will not be enough. My values, and the values of Carrefour do not allow for racism and violence", Bompard said.
He also called for a complete review of employee and sub-contractors' training on security, diversity and tolerance values, said a report.
Brazilian police used tear gas and rubber bullets Monday to disperse protesters marching against the death of a black man beaten to death by white guards at a Carrefour supermarket. Similarly, in Rio de Janeiro, around 200 protesters gathered outside of another Carrefour store location and shouted slogans. "Unfortunately, in Brazil, the Black man suffers from inequality and these things happen on a daily basis", he told The Associated Press.
Unsurprisingly, Brazil's Trump-like President Jair Bolsonaro has responded to the unrest by denying that racism exists in the country. It was the last country in the Americas to abolish slavery, in 1888.
