A Mexican national was arrested Wednesday for trying to smuggle black-tar heroin and methamphetamine into the United States at the DeConcini Port of Entry in Nogales, an official said.

Benjamin Fornes, 21, of Nogales, Sonora, was taken into custody after officers found nearly 15 pounds of heroin and nearly 4 pounds of meth in a spare tire of his Toyota SUV, said Edith Serrano, a Customs and Border Protection spokeswoman.

The drugs and vehicle were seized, and Fornes was turned over to federal authorities, Serrano said.
