A fight between inmates as part of rival drug gangs killed 44 in a prison near the city of Monterrey, Nuevo Leon, said local authorities Sunday.
Jorge Domene, spokesman for Public Safety of the State, told reporters that the victims were stabbed, stoned and beaten to death with sticks.
The inmates of the prison in Monterrey fear, about 140 kilometers from the border with Texas, including members of the Gulf of Mexico and the Zetas cartel agreement. It is unclear whether the fight was between these two groups, Domene said.
The struggle between the two cell blocks, each with about 750 prisoners may have been dismissed as a cover for an escape from the prison staged, he said. Domene said, disappeared by counting the dead, some officials have discovered, but do not yet know how.
Forty-four people died before the government took over control of the police two hours later.
