A large group of armed civilians ambushed a state police convoy in the Sierra Tarahumara of Chihuahua last night, killing four officers and wounding six others. At least one officer is missing.
The attack took place about 8:30pm at El Nogal, located between the communities of San Juanito and San Pedro in the municipality of Bocoyna.
The attackers, believed to belong to the crime gang called La Línea, launched grenades and Molotov cocktails at the convoy before opening fire with assault rifles.
The officers were returning to their operations base after arresting three armed individuals in San Juanito and turning them over to authorities in the city of Cuauhtémoc, the state Attorney General said.
State and federal security forces responded to the attack with a land and air deployment of police to locate the missing officer and search for the attackers.
