Mexican marines detained one of the sons of Mexico's most-wanted drug kingpin, Joaquin "El Chapo" Guzmán Loera, leader of the powerful Sinaloa cartel, the Navy said Thursday.

Marines detained Jesus Alfredo Guzmán Salazar in the western state of Jalisco thanks to intelligence work, the Navy said in a brief statement. It didn't say when the 26-year-old Guzmán Salazar was caught or offer any other details.

Earlier this month, the U.S. Treasury Department announced it had placed financial sanctions on Guzmán Salazar and his mother, Maria Alejandrina Salazar Hernández. That bars American citizens from doing business with them and allows authorities to freeze their assets in the U.S.

Guzmán Salazar and his father were indicted on multiple drug trafficking charges in the U.S. District Court for the Northern District of Illinois in August 2009, the department said.

Authorities in the U.S. and Mexico have said they believe Guzmán Loera has children with several partners, including a woman whom he married in an elaborate public ceremony in 2007 and who recently gave birth to twins in California. The Treasury Department described Salazar Hernández, 53, as a wife of Guzmán, without providing details.

In May, the department announced similar sanctions against Guzmán's sons Ivan Archivaldo "El Chapito" Guzmán Salazar, 31, and Ovidio Guzmán Lopez, 22.

Ivan Archivaldo Guzmán Salazar was detained in Jalisco state on money laundering charges in Mexico in 2005, but was later released. Guzmán López plays a significant role in his father's drug trafficking activities, the department said.

"El Chapo" Guzmán was put on the Treasury Department's list in 2001, the year he escaped from a maximum security prison hidden in a laundry truck. He has evaded authorities ever since, moving from hideout to hideout as he directs the operations of his cartel and a fight against rivals that has left thousands of people dead across Mexico.

In 2009, Forbes Magazine put Guzmán Loera on its list of the world's richest people, with an estimated $1 billion fortune.
