MEXICO CITY — The Mexican army announced Sunday that it had captured the head of security for Sinaloa drug cartel head Joaquin "El Chapo" Guzman, one of the world's most wanted men.

The suspect, who was not identified by name, was captured in the Sinaloa state capital of Culiacan and will be presented to the media Monday morning, the army said.

Guzman, Mexico's top drug lord, is one of the world's richest men, and has eluded authorities by moving around and hiding since his 2001 escape from prison in a laundry truck.
