Florida ? A Mexican national surrendered at the U.S. border Wednesday on allegations of abducting a 13-year-old from a Florida bus stop last month and leaving him tied up in the woods before the boy escaped, officials said.

Vicente Ignacio Beltran-Moreno, 22, agreed to voluntarily return from Mexico after several days of negotiations with the FBI, Manatee County Sheriff Charlie Wells said.

Beltran-Moreno was arrested Wednesday morning at the U.S.-Mexico border in Texas, and extradition proceedings were under way to get him back to Florida.

Clay Moore was grabbed Feb. 23 while waiting at his school bus stop in Parrish. The gunman drove off with him in a red pickup truck, then left him tied up in the woods about 20 miles away.

The boy’s parents have said he freed himself by using a safety pin to pick apart the duct tape that held his wrists.
