U.S. Customs and Border Protection announced that officials at the Port of San Luis seized “high-powered assault weapons” from a 28-year-old American citizen crossing the border through the legal port of entry.

“Preventing these weapons from being smuggled into Mexico has undoubtedly saved lives,” Chris Leon, area port director for San Luis, said in a statement.

“Our CBP officers remain vigilant and eager to disrupt illegal activities that compromise safety and security in our communities on both sides of the border,” Leon continued.

Specifically, CBP said “five AK-47 rifles” and “two .50 caliber rifles” — along with several “magazines of ammunition” for both — were hidden inside a Chevrolet SUV, which was also , taken by federal authorities. The suspect was then referred to Homeland Security Investigations.

Seizures of drugs, such as fentanyl and methamphetamine, and weapons are common along the southern border. With the upcoming change of presidential administrations, the nation is watching how border policies will change when it comes to seizing illicit goods and stopping illegal immigration. Arizona has been particularly hard hit by the border crisis, with more than 565,000 migrants in fiscal year 2024 alone, as well as a high volume of catches as legal ports.
