13 people arrested in connection with drug lord El Chapo's escape
Another 13 people have been arrested over the prison escape of notorious Mexican drug capo Joaquin "El Chapo" Guzman.
The national Prosecutor's Office said 11 men and 2 women were arrested and taken to different jails.
It did not name the suspects but said they were detained in connection with the escape.
Earlier this month a judge began proceedings against four officials including two intelligence service members and two prison control room employees.
They were accused of aiding Guzman's July 11 escape through a tunnel dug to his cell.
El Chapo's escape was a global sensation, with pictures of the one-mile tunnel to freedom going around the world.
It is also alleged that up to €50m in bribes may have been paid to secure his escape from prison.
Proceedings were already under way against the person in charge of the control room and two prison guards.
Guzman also escaped from another prison in 2001.
Earlier this month, it was accidentally revealed via tweet from his son that Guzman was in Costa Rica but he remains at large.
