US says El Chapo's son surrendered but El Mayo taken against his will

The U.S. embassy in Mexico said on Friday that Joaquin Guzman Lopez, the son of the infamous cartel kingpin "El Chapo," had surrendered voluntarily while his father's former partner Ismael "El Mayo" Zambada seemed to have been taken against his will.

Both Zambada and Guzman Lopez have pleaded not guilty to drug trafficking charges in the United States and their lawyers offered contrasting versions of their arrests.
