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

The Mexican boxer was arrested by Immigration and Customs Enforcement (ICE) officers in Studio City, Los Angeles, five days after fighting Jake Paul in nearby Anaheim.

The 39-year-old has now been detained in a prison in the northern Mexico state of Sonora, the country's national arrest registry showed on Tuesday, as he awaits charges.

It said that the boxer was arrested at a checkpoint in the border city of Nogales on Tuesday morning and transferred to a federal institution in Sonora's capital of Hermosillo, according to BBC.
