Boxer Julio César Chávez Jr has been deported to Mexico, where he’s wanted for alleged cartel ties, following his arrest in the US for overstaying his visa and lying on a green card application.

Chávez was handed over by authorities and admitted to a prison in the northern state of Sonora, an official told The Associated Press on condition of anonymity.

Chávez, 39, had a warrant for his arrest in Mexico for alleged arms and drug trafficking and ties to the Sinaloa Cartel. Alejandro Gertz Manero, Mexico’s attorney general, said the investigation into Chávez started in 2019.

The boxer, who is the son of legendary Mexican fighter Julio César Chávez, was arrested July, three days after his high-profile fight with Jake Paul in California.

Mexican president Claudia Sheinbaum said after the arrest she hoped the boxer would be deported to face his charges.

Chávez’s father was a massive celebrity in the 1980s and ’90s who mixed social circles with drug dealers and claimed to have been friends with drug lord Amado Carrillo Fuentes.

The younger Chávez has battled drug addiction for much of his boxing career, failing drug tests, serving suspensions and egregiously missing weight while being widely criticised for his intermittent dedication to the sport.

Chavez won the WBC middleweight title in 2011 and defended it three times. He shared the ring with generational greats Canelo Álvarez and Sergio Martinez, losing to both.

In 2012, he was convicted of drunken driving in Los Angeles and sentenced to 13 days in jail. In January 2024, he was arrested on gun charges.

Police said he possessed two AR-style ghost rifles. He was later freed on a $US50,000 bond and on condition he went to a residential drug treatment facility. The case is still pending, with Chávez reporting his progress regularly.
