Thirteen people were arrested in Mexico after a connection was made between them and the jailbreak of drug lord Joaquin "El Chapo" Guzman.
Among the arrested is the former director central Mexico's high-security Altiplano prison, Valentin Cardenas, and the former director of Mexico's federal prisons, Celina Oseguera. 11 prison guards were also arrested, NBC News reports.
Additionally, four officials, including two from CISEN - Mexico's intelligence agency - were charged this month for their suspected parts in the drug lord's escape.
A total of 20 officials have now been arrested in connection with Guzman's escape from the maximum-security facility in July, Reuters in Yahoo News reports.
Guzman, also wanted in the U.S., is branded as the world's biggest drug lord. His escape was well thought of.
He disappeared from security cameras while in a shower room. Apparently, he dropped into a mile-long tunnel, at the end of which, was an elaborate modified motorcycle, complete with ventilation and lighting.
Officers took 18 minutes to reach the shower, by which time, "El Chapo" was no longer in the area, and has not been officially spotted since.
This is the drug lord's second escape from prison, the first of which took place in 2001.
There is a $3.8 million reward for Guzman's capture, CNN reports.
