MEXICO CITY — Prison guards apparently let inmates who belonged to the brutal Los Zetas gang bludgeon to death 44 rivals from the Gulf Cartel during a weekend riot, while other Zetas gangsters fled the prison, Gov. Rodrigo Medina of Nuevo Leon state said Monday.
Medina said 30 inmates, some of them senior Zetas gangsters, escaped the Apodaca prison, probably using Sunday's predawn melee as cover.
There were no signs that the fleeing inmates had escaped over prison walls or through tunnels, Medina said, indicating that they simply walked out the gates.
"Unfortunately, a group of traitors has set back the work of a lot of good police," Medina said during a news conference in Monterrey, the capital of Nuevo Leon. "It's painful for us to confirm that the treason, corruption and complicity of some could obstruct the service of good police officers, soldiers and marines."
Medina fired the prison's warden, his deputy and the state's director of penitentiaries. Authorities also detained for questioning the 18 guards who were on duty at the time of the riot.
Among the gangsters who escaped was Oscar Manuel "the Spider" Bernal Soriano, who was the Zetas boss in Monterrey, Mexico's third-largest city, at the time of his capture in October 2010. Bernal is accused of taking part in the execution of a retired army brigadier general and his four bodyguards in 2009.
Medina said the 30 escapees were Zetas. He offered a reward of about $780,000 for information that leads to their recapture.
The prison melee began around 2 a.m. Sunday, when Zetas inmates wielding clubs, rocks and makeshift knives attacked a cell block that housed members of the Gulf Cartel, stabbing and bludgeoning them to death. At least one man reportedly was beheaded. All the victims belonged to the Gulf Cartel, Medina said.
Soldiers arrived and quelled the riot within two hours.
