A Mexican immigration official has been arrested after US border inspectors found about 77 kilograms of marijuana in his pickup truck, a US law enforcement official said Monday.
The law enforcement official identified the Mexican as Francisco Celaya Carrillo.
The official said Carrillo told Customs and Border Protection officers that he was entering the United States to do some shopping.
In Tucson, Arizona, Customs spokesman Brian Levin confirmed that a pickup truck had been stopped at the border crossing. When it was examined with a noninvasive gamma-ray machine, Levin said, officials found "79 packages of marijuana, just shy of 169 pounds" in the spare tire and fuel tank.
