Joaquin "El Chapo" Guzman, Mexico's most infamous drug lord, has left his prison. Only this time he didn't escape.
Guzman, who has twice escaped federal prison in Mexico, was transferred from the Altiplano maximum-security prison outside Mexico City - the same prison he tunnelled out of last year - to a new lock-up in Ciudad Juarez, along the border with Texas.
Mexican authorities described the transfer as part of a regular shuffling of detainees to different facilities to help prevent escapes - some 7400 people have been moved around in a police implementation after Guzman's last break-out.
They also said in a statement that they were doing work to reinforce security in the Altiplano and Guzman's new prison, Cefereso No. 9.
But a former US Drug Enforcement Administration official, Mike Vigil, said he had been told by Mexican authorities that Guzman was moved because of fears about the security at Altiplano, considered the country's most impenetrable prison.
