Monterrey, Mexico: Vast luxuries such as saunas, mini-fridges, a bar, a king-size bed and food stands were discovered by authorities entering a prison in northern Mexico to investigate a riot that killed 49 inmates.
Nuevo Leon state authorities said in a statement the cells inside Monterrey's Topo Chico prison were equipped with mini-fridges, airconditioners, digital cable and aquariums. There were 280 food and grocery stands where inmates could buy goods.
The riot broke out on Thursday between two rival factions of the Zetas drug cartel.
Zetas drug cartel leader Ivan Hernandez Cantu, alias "El Credo", had a king-sized bed in his cell, a huge flat-screen television and a luxury bath, the Nuevo Leon state prosecutor's office said, according to Agence France-Presse.
"At the time of the attack, a lady was with him," chief prosecutor Roberto Flores said.
Heavy machinery was brought in to haul away tons of contraband furniture and other goods that authorities had piled in the prison yard, the statement said.
It added that police destroyed hundreds of altars to the Death Saint. The folk figure is revered by drug traffickers and some people among the downtrodden.
"We knew about all of the irregularities that existed, arbitrary acts, abuses, taxes," General Cuauhtemoc Antunez, the state's security secretary, said in the statement. Authorities did not say how long the abuses had occurred or who allowed them.
Nuevo Leon Governor Jaime Rodriguez said last week that 60 hammers, 86 knives and 120 shivs were used in the melee.
The prison's director, superintendent and a guard have been arrested on murder charges.
On Monday, a United Nations official called on Mexico's government to conduct an exhaustive investigation of a prison riot that killed 49 last week.
Special rapporteur for torture Juan Mendez said in statement that the government must guarantee that the victims' families know what happened during the Thursday riot at the Topo Chico prison in the northern city of Monterrey.
The investigation should identify those responsible and include reparations for the victims' relatives, Mr Mendez said.
The UN official toured the prison in 2014. He said he witnessed horrible conditions and lax rules that allowed prisoners to govern themselves and led to violence.
