Famed Mexican boxer Julio César Chávez Jr. has been arrested for entering US illegally and will be deported to Mexico, where he faces organized crime charges, federal officials said Thursday. The arrest in Studio City, California, on Wednesday comes only days after the former middleweight champion fought in a match against Jake Paul in Anaheim, California. The Department of Homeland Security said Immigration and Customs Enforcement officers detained Chávez for overstaying a tourist visa. They said he also has an active arrest warrant in Mexico for involvement in organized crime and trafficking firearms, ammunition, and explosives and is believed to be an affiliate of the Sinaloa Cartel.
