SAN CLEMENTE – Two men suspected of smuggling more than 12 pounds of methamphetamine were stopped at a freeway checkpoint on Tuesday, authorities said.

The two men – a U.S. citizen who was driving a Ford F-150 and a Mexican national who was a passenger in the pickup – were stopped around 6 p.m. at the Interstate 5 checkpoint near San Clemente, according to a U.S. Border Patrol statement.

After the passenger was unable to provide agents with a visa, he admitted to being in the country illegally, authorities said.

A police canine alerted agents to the presence of drugs, and with the assistance of an x-ray detection system they found bundles of methamphetamine hidden in various parts of the pickup, according to the statement.

The driver and passenger, who have not been identified, were arrested. They, along with the drugs, were turned over to the Drug Enforcement Administration.

Border Patrol officials estimate the approximately 12.24 pounds of methamphetamine found in the vehicle has an estimated street value of about $122,400.
