Drug gangs sparked a prison riot that killed 56 people, with decapitated bodies thrown over prison walls in the bloodiest violence in more than two decades in Brazil’s overcrowded penal system, officials said on Monday.
Sergio Fontes, the security chief for Amazonas state, told reporters several decapitated bodies were thrown over the wall of the prison in the Amazon city of Manaus, with most of those killed coming from the São Paulo-based First Capital Command (PCC) drug gang.
“This was another chapter in the silent and ruthless war of drug trafficking,” he said.
Pedro Florencio, the Amazonas state prison secretary, said the massacre was a “revenge killing” in a feud between criminal gangs in Brazil.
The violence began late Sunday and was brought under control on Monday morning, Mr Fontes said.
Just as the riot began in one unit of the Anisio Jobim prison complex, dozens of prisoners in the second unit started a mass escape in what authorities said was a co-ordinated effort to distract guards.
Overcrowding is extremely common in Brazil’s prisons, which suffer endemic violence and what rights groups call medieval conditions with food scarce and cells so packed that prisoners have no space to lie down.
The Anisio Jobim prison complex houses 2,230 inmates despite having a capacity of only 590.
Hours after the Anisio Jobim prison revolt ended, prisoners at an adjoining detention centre began a riot and attempted to escape. Authorities said the situation was quickly brought under control.
Watchdog groups sharply criticise Brazil for its prisons, where deadly riots routinely break out.
“These massacres occur almost daily in Brazil,” said Father Valdir Silveira, director of Pastoral Carceraria, a Catholic centre that monitors prison conditions in Brazil. “Our prisons were built to annihilate, torture and kill.”
A total of 184 inmates escaped, with 40 recaptured by Monday afternoon.
The violence was the latest clash between inmates aligned with PCC, Brazil’s most powerful drug gang, and a Manaus criminal group known as the North Family.
The Manaus-based gang is widely believed to be attacking PCC inmates at the behest of the Rio de Janeiro-based Red Command (CV) drug gang, Brazil’s second largest.
“This is part of a nationwide movement. It has happened in Roraima, in Acre, Porto Velho, in parts of north-east Brazil and now it has happened here,” Amazonas Governor José Melo de Oliveira said at a news conference, referring to other clashes between rival criminal factions.
Mr Oliveira met on Monday with justice minister Alexandre de Moraes and other federal security officials over the riot. Speaking at the same news conference, Mr Moraes said that once identified, inmates who spearheaded the revolt would be transferred to federal prisons.
Four inmates were later found dead in another prison in the rural area of Manaus, but state representatives were unable to clarify if a riot had occurred.
Security analysts have said a truce that held for years between the PCC and CV was broken last year, resulting in months of deadly prison battles between the gangs and sparking fears that chaos would spread to other prisons.
In the latest riot, a group of inmates exchanged gunfire with police and held 12 prison guards hostage late on Sunday in the largest prison in Manaus, an industrial city on the banks of the Amazon River, Globo television reported.
Mr Fontes said 74 prisoners were taken hostage during the riot, with some executed and some released.
A video posted on the website of the Manaus-based newspaper Em Tempo showed dozens of bloodied and mutilated bodies piled on the prison floor as other inmates milled about.
Sunday’s riot was the deadliest in years. A 1992 rebellion at the Carandiru prison in São Paulo state saw 111 inmates killed, nearly all of them by police retaking the jail.
Maria Canineu, director of Human Rights Watch for Brazil, said the most recent violence was the result of “no government in 20 years giving much attention to the penitentiary system”.
Ms Canineu said it has been difficult for years for states to receive any funding help from the federal government for prisons.
President Michel Temer announced last week that the federal government would furnish states with 1.2bn reais ($366m), mostly to improve infrastructure and security in existing prisons and to build new ones.
