The riot began late on Sunday and was suppressed only at 8:40 a.m. local time (12:40 GMT), according to the television channel.
Police seized four handguns, a shotgun and improvised weapons from prisoners, the news channel said.
Earlier in the day, local media reported that at least 50 prisoners were killed in the riot, which was sparked by the clashes between two opposing gangs in the prison of the city of Manaus.
