Mexico's government has admitted that it mistakenly identified a detained man as the son of the country's most-wanted drugs lord, Joaquin "El Chapo" Guzman.

On Thursday officials paraded before the media a man they said was Jesus Alfredo Guzman, whose father leads the powerful Sinaloa cartel.

But the arrested man was in fact Felix Beltran Leon, a car salesman, the attorney general's office said.
