Shortly before 1900 hours on Sunday there was another attack against the personal bodyguards of the governor of Nuevo León, Rodrigo Medina.
Early reports indicate that an unknown group of heavily armed men attacked the guards that were patrolling in an official vehicle on a major route in Monterrey.
At present time there is an intense operation by the authorities in the area of Avenida Morones Prieto and San Francisco, by the tunnel Loma Larga, in the vicinity of Casa de Gobierno.
The authorities attempted to deny the incident they did in previous occasions, however a very close source confirmed the incident.
So far it is known that at least one person was killed.
