In a statement, the authorities said that the riot was caused by a fight between prisoners from two wings and that at least 10 had been confirmed dead. Television reports from the scene described gunfire and showed images of inmates on the prison roof. Four days later, 33 prisoners were killed and many were dismembered at a prison in Boa Vista in Roraima State, in the far north of Brazil. Then four more prisoners were killed in a third Manaus prison after being moved from the site of the first massacre. Ms. Azevedo said that the gang, known by its Portuguese acronym, P.C.C., and a Rio Grande do Norte gang called the Crime Syndicate were involved in the riot on Saturday.
