Here are the latest developments about Mexican drug lord Joaquin "El Chapo" Guzman's escape from prison:
Republican presidential hopeful Donald Trump has seized on the dramatic prison escape of drug lord Joaquin "El Chapo" Guzman to add to his recent criticism of Mexico.
The tweet from his official site @realDonaldTrump on Sunday pointed to the escape as a reminder of problems he was referring to when he said that many Mexican migrants bring drugs and crime to the United States.
Trump's Twitter message says: "Mexico's biggest drug lord escapes from jail. Unbelievable corruption and USA is paying the price. I told you so!"
Some Republican leaders who hope to make inroads with Hispanic voters in the U.S. have urged him to tone down his criticism of Mexican immigrants, to no avail.

A crime-fighting group in Illinois says that Joaquin Guzman's escape from a Mexican prison means the man known as "El Chapo" will regain his title as Chicago's Public Enemy No. 1.

Security Commissioner Monte Alejandro Rubido tells a news conference Sunday that Guzman used an elaborate escape hatch built allegedly without the detection of authorities.
With his escape Guzman has done what Mexican authorities promised would not happen after his re-capture last year — to slip out of a maximum security prison for the second time.
Rubido says 18 employees from various part of the Altiplano prison 90 kilometers (56 miles) west of Mexico City have been taken in for questioning.
