The human rights organisation Amnesty International said on Monday that extra-judicial executions by police officers are frequent in Brazil and denounced Rio de Janeiro's police for what it calls "unnecessary, excessive and arbitrary" use of force.
In a report released on Monday, the group said Rio's police operate with "total impunity," regularly executing mostly young, mostly black and mostly poor people in the city's violent favelas.
It said police often try to cover up the executions by alleging victims were killed in firefights or by planting weapons on the corpses.
The report was based on an investigation into ten police killings in 2014 and 2015 in the Rio favela of Acari, which found that four of the victims were wounded or had surrendered before they were killed, another four were fired on without warning, while another was fleeing from police when he was gunned down.
Hundreds of people are killed by police during security operations in the state of Rio de Janeiro each year.
The Amnesty report quoted official statistics as recording 285 people killed by police in the first half of 2014 - a 37 percent increase on the same period in 2013.
Brazil has more homicides than any other country, with some 56,000 people slain in 2012.
