The Investigations Police of Chile (PDI) didn't specify a reason for denying Tyson the opportunity to set foot in Chile. The AP reported Tyson's criminal record may have played a role in the decision.
The PDI shared a photo of officers escorting Tyson through the Comodoro Arturo Merino Benítez International Airport in Santiago, Chile:

According to the AP, Tyson had traveled to Chile to take part in a promotional event for a local television channel.
Tyson was released from prison in 1995 after serving three years of a 10-year sentence for rape. The 51-year-old served four months in prison in 1999 after assaulting two motorists a year earlier. He also pleaded guilty to cocaine possession and driving under the influence in 2007.
