WASHINGTON (AP) -- New details are emerging about the arrest of one of the world's most wanted drug lords.
A U.S. government official and a senior federal law enforcement official say cellphone intercepts and the arrests of a courier and top aide to Joaquin "El Chapo" Guzman led to his arrest early Saturday.
The officials say U.S. and Mexican authorities found a cellphone belonging to the aide on Feb. 16 at a house where drugs were stored.
Another wiretap run by Immigration and Customs Enforcement led authorities to the beachfront condo where Guzman was taken into custody.
Guzman was armed with a military-style assault rifle when he was arrested.
The officials spoke on the condition of anonymity because they were not authorized to discuss details of the investigation.
House panel chair seeks "El Chapo's" extradition
The chairman of the House Committee on Homeland Security is encouraging Mexico's authorities to extradite drug kingpin Joaquin "El Chapo" Guzman to the United States to ensure he remains behind bars.
Texas Republican Michael McCaul calls Guzman the world's most notorious drug lord and tells ABC that his arrest is a significant victory for Mexico and the United States.
Guzman faces at least seven federal indictments in the U.S.
McCaul says it's Mexico's call on where Guzman faces prosecution, but he notes that Guzman escaped from prison in 2001 and corruption continues to plague Mexico.
McCaul says Guzman would end up "in a super-max prison" in the U.S. from which he could not escape.
