Mexican boxer Julio Cesar Chavez Jr. was detained and is in the process of being deported from the United States just days after fighting social media influencer Jake Paul in a high-profile bout.

Julio César Chávez Jr. is the firstborn son and namesake of the man considered the best Mexican boxer in history.

The DHS said Chavez, a Mexican citizen, had an active arrest warrant against him in Mexico for what it said was his involvement in organized crime and trafficking firearms, ammunition, and explosives.
