Mexican boxer and the son of the legendary fighter Julio Cesar Chavez, has been arrested by Immigration Customs Enforcement (ICE) agents over his alleged links to the powerful Sinaloa cartel.
Julio Cesar Chavez Jr, 39, was arrested on Wednesday by federal agents in Studio City, California, 10 miles north of Los Angeles.
Over the weekend he fought, and lost, against the former YouTuber Jake Paul at the Honda Centre in Anaheim, California.
Officials said that while Mr Chavez Jr had overstayed a tourist visa, Mexican authorities had an active arrest warrant against him for what it claimed was involvement in organised crime and trafficking firearms and ammunition.
The Department of Homeland Security (DHS) said Mr Chavez Jr, a former world title holder, was “believed to be an affiliate of the Sinaloa cartel”.
