Nogales, Arizona – Federal agents delivered a major blow to the Sinaloa Cartel after discovering and raiding a sophisticated underground tunnel stretching from Mexico into Arizona, seizing a staggering 4 tons of cocaine and arresting 62 individuals in a high-intensity operation.
On March 15, 2026, DEA and ICE Homeland Security Investigations teams, working with Border Patrol and local law enforcement, stormed a warehouse in the Nogales area and uncovered a professionally engineered cartel tunnel equipped with ventilation systems, lighting, rail tracks, and reinforced walls. The tunnel extended nearly 400 yards across the border and was being used as a major superhighway for smuggling mᴀssive quanтιтies of cocaine into the United States.
Agents seized approximately 4 tons (8,000 pounds) of high-purity cocaine with an estimated street value exceeding $120 million. They also recovered large amounts of cash, firearms, and drug packaging equipment inside the tunnel and connected stash houses.
Sixty-two individuals were arrested during the raid, including several high-ranking cartel operatives and tunnel operators. Authorities say many of those detained had direct links to Sinaloa Cartel factions responsible for flooding Arizona and the Southwest with ᴅᴇᴀᴅly drugs.
This discovery highlights the cartels’ relentless innovation in building elaborate underground infrastructure to evade border security. The tunnel was one of the most advanced found in recent years, demonstrating how criminal organizations continue to adapt and expand their operations despite increased enforcement.
DEA officials called the operation a significant victory in the fight against cartel smuggling networks. The seized cocaine alone could have poisoned communities across multiple states for months.
The message from this raid is unmistakable: American law enforcement is aggressively hunting cartel tunnels and will not allow these criminal organizations to turn U.S. soil into their private distribution network. Every tunnel found and every ton seized weakens their ᴅᴇᴀᴅly empire.
Arizona and the entire Southwest just received a powerful reminder that the battle against cartel infiltration is intensifying — and federal agents are striking back hard.
