Sean Penn interview helped nab Mexico drug lord "Chapo" Guzman

By Lizbeth Diaz and Simon Gardner MEXICO CITY (Reuters) - An interview that Hollywood star Sean Penn conducted with Mexican Joaquin "Chapo" Guzman late last year helped Mexico's government catch the world's most wanted drug lord, sources said on Saturday. Guzman told Penn in the interview published in Rolling Stone on Saturday that he sent tunnel engineers to Germany for training prior to his prison break through a mile-long passage to his cell last year. Guzman, the legendary boss of the Sinaloa drug cartel, was arrested in northwest Mexico on Friday morning, and sent back to the jail he broke out of in July through a mile-long tunnel that led straight into his cell.
