The secret escape route of drug lord Joaquin 'El Chapo' Guzman has been shown for the first time in bodycam footage.

In a newly released video Mexican marines can be seen smashing through the steel-reinforced front door to Chapo's safehouse before conducting a search.

A hidden set of steps underneath the bath was discovered during the operation, revealed where Guzman's brazen escape was made.

His mistress, Lucero Guadalupe Sanchez Lopez, told a New York courtroom on Friday that Chapo was "naked" when he made his exit.

“He took off running,” she said. “He left us behind.”
