The twelve criminals broke out from the Aquiles Serdan prison in Chihuahua State located approximately four kilometers (two miles) from the state's capital of Chihuahua. The prison break took place at about 5.00 a.m. local time.
Local officials said that a loud blast was heard and initially it was thought that a grenade had exploded. However, it was later determined that the explosion was only a distraction while a vehicle demolished a wire fence.
The vehicle left a hole with one meter and a half of diameter through which the twelve inmates fled. At about 8.20 a.m., police forces managed to capture one of the twelve criminals who escaped through the west side hole.
