Mexico's most wanted man, drug kingpin Joaquin "Shorty" Guzman, has been captured in Mexico by US and Mexican law-enforcement officials, sources said yesterday, in what would mark a major coup in a grisly fight against drug gangs.

A US government source said Guzman had been captured, without elaborating. A Mexican security source said he was caught in Mazatlan, a seaside resort in Guzman's home state of Sinaloa.

Guzman runs Mexico's infamous Sinaloa Cartel which has been fighting a brutal war with other gangs.
