MEXICO CITY - Mexican authorities have notified recaptured drug lord Joaquin "El Chapo" Guzman that he is wanted in US, beginning proceedings to extradite him to face charges in America.

Guzman was arrested early Friday after a shootout in his home state of Culiacan that killed five and injured one marine.

Mexican authorities said the arrest is partially due to a secret interview Guzman did recently with actor Sean Penn, which helped authorities locate the world's most notorious drug kingpin. The official, who is speaking on condition of anonymity, says it was the Penn interview that led authorities to Guzman in a rural part of Durango state in October. They aborted their raid at the time because he was with two women and child.

Attorney General Arely Gomez also said Guzman's contact with actors and producers for a biopic helped gave law enforcement a new lead on tracking and capturing him.

In an article published late Saturday in Rolling Stone, and authored by Penn, the actor describes the complicated measures he took to meet the legendary drug lord. He says he discussed topics ranging from drug trafficking to Middle East politics with Guzman.

Rolling Stone says the meeting between Guzman and Penn was brokered by Mexican actress Kate del Castillo.
