Chavez Jr., the son of former three-division world champion of boxing Julio Cesar Chavez and older brother of Omar Chavez, held the WBC's middleweight title from 2011 to 2012 and has an all-time record of 54-7-1. His arrest comes just days after his most recent match, a loss to Jake Paul at Honda Center in Anaheim, Calif.

The Department of Homeland Security said Chavez Jr. is in the process of being deported from the U.S. over alleged cartel ties and other infractions.
