U.S. Border Patrol agents from Blythe arrested a convicted sex offender suspected of being in the United States illegally.

Jorge De Jesus-Martinez, a resident of the town of Querétaro in central Mexico, crossed into the United States in Arizona, said Ben Vik, spokesman for the Border Patrol's Yuma sector.

"He ... walked through the desert for four days before being picked up by a vehicle, transferred to another vehicle, and that vehicle was picked up by the Arizona Department of Public Safety," he said.

De Jesus-Martinez was taken to a jail in Kingman, Ariz., Vik said. Border Patrol agents determined he was in the country illegally and took him into their custody.

The U.S. Border Patrol said it would work to deport De Jesus-Martinez to Mexico.

Vik said De Jesus-Martinez had been charged with rape and sexual battery in 2008, when he was living in Stockton. He was convicted of both counts and deported through Calexico in September.
