Joaquin Guzman, one of the worlds most wanted drug traffickers has escaped from a top security prison, and this isn’t the first time.

He most recently escaped from Altiplano jail, where he fled down a mile long route complete with ventilation, lighting and stairs. Officials find it hard to believe he pulled this off without any inside help.

He was last seen in the showers of the jail this past Saturday. When officers checked his cell later that day they discovered he had disappeared. They found a hole with a latter leading to a tunnel. At the end of the tunnel was a construction site outside of the prison walls.

Guzman has been serving his time for more than 20 years after first being arrested in Guatemala in 1993 due to leading the Sinaloa Cartel, which smuggles large amounts of cocaine, marijuana and methamphetamine into the U.S.

The second escape is not only an embarrassment to Mexico, but also a huge problem. If Guzman is to be recaptured, who’s to say he won’t make a run for it a third time.

The U.S government is working with Mexico to help recapture the dangerous drug lord, according to BBC. A manhunt is now in place.
