Customs officers southwest of Tucson seized more than a ton of marijuana from a motorhome being driven by a Phoenix man, the CBP said in a news release.

The drugs had a street value of about $1.2 million, according to Customs and Border Protection.

On Saturday, CBP officers at the Lukeville port sent a motorhome trying to enter Arizona to a secondary inspection after a drug dog alerted to the vehicle. Officers found 120 bundles of marijuana hidden in storage compartments, walls and under the floor of the motorhome, the CBP said.

The drugs weighed nearly 2,500 pounds and represents the second-largest marijuana seizure at the Lukeville port.

Officers seized the vehicle and drugs and turned the 55-year-old man over to U.S. Immigration and Customs Enforcement's Homeland Security Investigations.
