Police investigators said yesterday that the officers are suspected of torturing and killing Amarildo de Souza in the Rocinha slum. He was a bricklayer and the father of six children.
Investigators believe the officers later discarded Souza's remains, which have not been found.
Under Brazilian law, prosecutors now have 30 days to decide whether to file charges against the officers.
The case sparked outrage in Brazil, with protesters taking to the streets demanding that police be held accountable in the case.
