Heavy fighting in Mexico as El Chapo’s son goes free

The Mexican authorities have been forced to release a son of the jailed drug lord, 'El Chapo' Guzman, after ferocious gun battles between gang members and the security forces in Sinaloa state. Fighting raged for hours after Ovidio Guzmán López was found and seized during a routine patrol in the city of Culiacán. Authorities say Mr Guzmán was released to avoid further violence.
