SAO LUIZ, Brazil, Feb. 9 (UPI) -- Six inmates, including one convicted of fathering several children with his two daughters, were killed in a brutal melee in a Brazilian prison, authorities say.
Jornal Pequeno reported Wednesday four of the inmates slain at Complexo Penitenciario de Pedrinhas in northeastern Brazil were beheaded, including Jose Agostinho Pereira, a 54-year-old farmer arrested in June 2010 and sentenced to 63 years for sexually abusing his daughters.
The riot, involving about 100 prisoners, started Monday night and the situation wasn't brought back under control until Tuesday afternoon, the Brazilian newspaper reported.
The prisoners ended their uprising only after being promised there would be no retaliation against them and they would be transferred to other facilities, the newspaper said.
Authorities recovered handmade knives, iron rods and other weapons.
