Federal, state, and local law enforcement agencies, led by the FBI, conducted a large-scale raid on the La Catedral Horse arena in Wilder, Idaho, targeting an illegal gambling operation linked to horse racing and animal fighting. The operation resulted in the arrest of five individuals, including the property owner Ivan Tellez, and the detention of 105 undocumented immigrants who attended the event, none of whom were children. The raid was part of a months-long investigation into criminal activities involving illegal gambling, drug trafficking, and weapons, with authorities emphasizing the common practice of detaining attendees during such operations for safety and evidence preservation.

Idaho Governor Brad Little and the Department of Homeland Security (DHS) supported the enforcement action, highlighting the connection between illegal gambling and broader criminal networks, including cartel involvement. The DHS confirmed the arrests and detentions as part of efforts to dismantle criminal enterprises in the U.S. Legal assistance is being provided to detainees, with some released and others held in facilities across Idaho and Utah. The community expressed concern over the detention of children, but officials clarified that no minors were taken into custody.
