There were also attacks in the states of Guerrero and Guanajuato. The gunmen tossed hand grenades and opened fire on police stations and at the hotel installations where the officers slept in six major Michoacan cities. A few hours after Rueda's arrest, convoys of heavily armed gunmen ambushed federal forces across the western state of Michoacán.

Rueda Medina was then taken to Mexico City by dozens of policemen and soldiers. Minutes later, a group of more than two dozen gunmen tossed fragmentation grenades and opened fire on the federal police offices where Rueda Medina was being held. Arrest Īfter six months of police intelligence, Rueda Medina was arrested on 11 July 2009 by elements of the Mexican Federal Police while he was arriving at his residence in the capital city of Morelia, Michoacán. He was also responsible for assigning regional leaders of the cartel, contacting international drug suppliers, and infiltrating several police forces where La Familia Michoacana held a stronghold. By 2006, he was in charge of coordinating the cartel's narcotics fabrication and smuggling operations. But after the arrests of Rosales Mendoza and of the Gulf Cartel leader Osiel Cárdenas Guillén, Rueda Medina's group broke relations with Los Zetas along with Méndez Vargas and Moreno González. During the mid-2000s, Rosales Mendoza headed the cartel and aligned with the Gulf Cartel and Los Zetas to fight the Milenio Cartel. He reportedly started working for the cartel in 2000, when the drug lords Carlos Rosales Mendoza, José de Jesús Méndez Vargas, and Nazario Moreno González were fighting against the Valencia brothers of the Milenio organization for the control of the smuggling routes in western Mexico.

In 2004, he became the La Familia Michoacana's hitmen lieutenant responsible for tracking down cartel rivals and ordering gunmen to kill members of the Milenio Cartel, which had an alliance with the Sinaloa Cartel. Rueda Medina was born on 15 December 1969 in Parácuaro, a municipality of the state of Michoacán, and first worked as a tortilla seller before deciding to start his criminal career by stealing automobiles in the year 2000.

Rueda Medina was allegedly in charge of operations under La Familia leaders Nazario Moreno González and José de Jesús Méndez Vargas, who are both on Mexico's most-wanted list of drug suspects. Arnoldo Rueda Medina (born 15 December 1969) is a former Mexican drug lord and high-ranking leader of La Familia Michoacana, a drug trafficking organization which is based in Michoacán, Mexico.
