Former world middleweight champion Julio Cesar Chavez Jr. was recently arrested in the United States. According to the Mexican Prosecutor's Office, the boxer has alleged ties to the Sinaloa Cartel, one of the most powerful criminal organizations in Mexico.

The Attorney General's Office (FGR) has revealed shocking details about his alleged role within the group, in an investigation released this Friday by the newspaper Reforma.

Ties to the Sinaloa Cartel: accused of acting as a “punisher”

Most seriously, the Mexican FGR has revealed that Julio Cesar Chavez Jr. would have acted as a “henchman” or executor of physical punishments within the Sinaloa Cartel, specifically under the orders of Nestor Ernesto Perez Salas, alias “El Nini,” one of the organization's main security chiefs.

According to Mexican authorities, three key sources support the accusation:

In one of those calls, a disturbing episode is described that occurred in a cartel safe house, where “El Nini” allegedly ordered a subordinate to be hung like a punching bag so that Chavez could be killed. Jr. beat him as punishment for taking his partner to a warehouse with weapons and kidnapped people.

Chavez Jr.'s partner is also under suspicion

The former champion's legal situation is further complicated by the background of his partner, who is linked to the Sinaloa Cartel after having had a romantic relationship with a deceased son of Joaquin "El Chapo" Guzman.

This reinforces the authorities' hypothesis about a direct and active connection between Chavez Jr. and the criminal structure.
