U.S. Customs and Border Protection officers at the Gateway International Bridge seized a package of fentanyl hidden in a car.
According to a CBP news release, on Sunday officers ordered a Mexican national driving a 2010 Chrysler 300 to undergo a secondary inspection.
When the sedan was scanned, officers say they found a package of the narcotic weighing 2.39 pounds hidden inside the vehicle.
The 33-year-old man was arrested and turned over to Homeland Security Investigations (HSI) special agents. The car and drugs were seized.
