The U.S. Customs and Border Patrol released a statement over the weekend that indicated a man who had thrown rocks at a Yuma Sector Border Patrol agent and a CBP pilot claimed to have been part of the migrant caravans approaching the southern border.

The statement read: "On Friday night, at approximately 5:45 p.m., Yuma Sector Border Patrol agents discovered footprints from a subject who had illegally crossed from Mexico into the United States just east of the Andrade, Calif. port of entry. Agents radioed for a CBP Air and Marine helicopter to assist and it responded a short time later. The agents tracked the suspect for almost a mile until he was encountered near a tree. The male suspect climbed up into the tree, set it on fire and began to throw rocks at agents on the ground as well as at the CBP helicopter. None of the agents nor the helicopter was struck."

The subject—identified as a 31-year-old Honduran national illegally in the United States—told arresting agents that he had been part of one of the migrant caravans that had been covered by the media in Mexico recently.

He was taken into custody at the scene.
