A BRAZILIAN man who fathered seven children with his daughter by raping her was decapitated in a jail house riot.

Jose Agostino Pereira, 55, was brutally murdered alongside five other prisoners. Four in total - all accused pedophiles - were beheaded by the rampaging inmates.

"After 15 hours of rebellion, police in Maranhao dominated rebel prisoners from Pinheiro. The rebels killed six inmates accused of pedophilia and beheaded four of them. The riot began at 22.30 on Monday and finished yesterday [Tuesday at 1pm local time]. Among the victims is the farmer Jose Agostinho Pereira, the "Monster of Maranhao," Estadao.com.br reported Wednesday.

The police station lockup, located about 2250 kilometers north of Rio de Janeiro, had a 30-prisoner capacity but was housing 97 inmates at the time of the riot.

The decapitated prisoners, including Pereira, were killed with makeshift weapons fashioned out of prison bars. The rioters reportedly requested a kilo of cannabis as ransom for freeing other hostages and putting an end to the uprising.

Pereira lived until his arrest last June in a remote fishing village in Brazil, which was so isolated that the only way to reach it was by canoe. He was also accused of abusing one of the girls he had with his daughter. The alleged abuse began when Pereira's wife left him in 1998.

Police who freed the woman and her children last year said they appeared to be suffering from malnutrition and could hardly communicate. Most of them were not wearing any clothes. A police officer involved in the investigation said last year that Pereira had confessed to "everything."

Pereira was quickly dubbed Brazil's answer to notorious Austrian pedophile Josef Fritzl, who was sentenced to life in prison in 2009 after fathering seven children by repeatedly raping his imprisoned daughter Elisabeth.
