Story highlights Joaquin "El Chapo" Guzman tells his lawyer guards aren't letting him sleep

"They are turning me into a zombie," the Sinaloa cartel boss said, according to his attorney

(CNN) Now that he's back in a maximum-security prison, notorious Sinaloa cartel boss Joaquin "El Chapo" Guzman isn't happy about life behind bars, according to his attorney.

In an interview with Mexico's Radio Formula on Tuesday, Guzman's lawyer said the drug kingpin feels that he is a victim of "physical and mental torture" because guards wake him up so often.

"He told me, literally, 'Every two hours, at night, they wake me up to take roll. ... They are turning me into a zombie. They do not let me sleep. All I want is just for them to let me sleep,' " attorney Juan Pablo Badillo said.

The prison has installed 400 new cameras. Authorities hope to add another 600 by April. According to a report in Mexico's "El Universal" newspaper last month, motion sensors now monitor his every move, dogs have been trained to detect his scent stand guard and prison floors have been reinforced with steel rods.
