PHOENIX, Ariz.—U.S. Customs and Border Protection officials announced Thursday their biggest fentanyl bust ever, saying they captured nearly 254 pounds (114 kilograms) of the deadly synthetic opioid from a secret compartment inside a load of Mexican produce heading into Arizona.
The drug was found hidden in a compartment under the rear floor of a tractor-trailer on Jan. 26 after a scan during a secondary inspection indicated “some anomalies” in the load, and the agency’s police dog team alerted officers to the presence of drugs, Nogales CBP Port Director Michael Humphries said.
