Two 16-year-old boys were arrested Saturday in separate marijuana smuggling attempts at the Douglas port of entry.

The teens were both from Agua Prieta, Sonora, federal authorities said.

In the first incident, a teen driving a Ford sedan was referred for an additional inspection.

A narcotics detection dog alerted to the presence of drugs, and officers found 74 packages of marijuana throughout the car, said federal authorities.

The marijuana weighed nearly 67 pounds, and was valued at more than $33,000, authorities said.

In the second incident, a teen driving a Chevrolet pickup was also referred to a secondary inspection. Authorities found 15 packages of marijuana, weighing nearly 241 pounds in the truck, said officers.

The marijuana was valued at more than $120,000.

The drugs and both vehicles were seized. The teens were turned over to U.S. Immigration and Customs Enforcement's Homeland Security Investigations officials.
