Son of Mexican druglord released by rival gunmen

(Vatican Radio)  The youngest son of Mexico's Sinaloa drug cartel leader Joaquin "El Chapo" Guzman has been released safe and well after being abducted by rival gunmen.

Listen to James Blears's report:

Alfredo Guzman was abducted with five other men by seven gunmen from the Jalisco new generation drug cartel in a restaurant at the international vacation resort of Puerto Vallarta, in the early hours of the morning, exactly a week ago.

An unnamed relative of his confirms they were all release, after intense negotiations leading to major concessions, which haven't been specified.

Meanwhile, Mexican government officials say they are investigating if municipal police in Puerto Vallarta were involved in this kidnapping. 

Alfredo's imprisoned father, Joaquin "El Chapo" Guzman, led the Sinaloa drug cartel until his re-capture in January.

He's fighting extradition to the United States. Both father and son are wanted there on an array of drug trafficking charges.

More than 150,000 people have died in Mexico's ongoing nine year Drug War.
