The pilot who flew drug kingpin Joaquin "El Chapo" Guzmán to freedom has been arrested, Mexico's attorney general announced Thursday.
Arely Gomez Gonzalez said 23 government employees and 10 civilians had been detained in a quest for answers.
It was not clear when the pilot was arrested.
Guzmán, the chief of the Sinaloa cartel, busted out of the maximum security prison Altiplano in July through a mile-long tunnel before being flown out of the reach of police.
Earlier this week, a Mexican newspaper reported that two prison guards were playing solitaire while the kingpin escaped.
Guzman had previously escaped from prison in 2001, and was only recaptured last year. The second jailbreak was a huge embarrassment for Mexico’s President Enrique Pena Nieto, who had declared that it would be “inexcusable” if Guzman managed to escape again.
