Former boxing champion Julio César Chávez Carrasco, son of the Mexican boxing legend, was arrested on Monday in Hermosillo after the U.S. government deported him to his home country. Mexico’s Attorney General’s Office (FGR) accuses him of organized crime and arms trafficking, charges that link him to the Sinaloa Cartel.

Former world champion Julio Cesar Chavez Jr has been jailed in his native Mexico after his arrest in the United States in July.
