CBP agents at the Lukeville Port of Entry arrested four U.S. citizens and seized more than 2,800 pounds of marijuana in two separate Easter weekend smuggling attempts.

On Saturday, a 55-year-old man from Glendale traveling with a 58-year-old woman from Phoenix were sent for a secondary inspection of his motorhome, according to a news release from Customs and Border Protection.

A CBP drug dog led officers to multiple marijuana bundles, weighing more than 2,600 pounds and valued in excess of $1.3 million.

On Sunday, officers sent a 40-year-old man from Green Valley and his 24-year-old female passenger for further inspection of his Ford truck. With the aid of a drug dog officers found more than 150 pounds of marijuana, worth almost $77,000, within the truck’s bed.

Officers seized the drugs and vehicles, and turned the suspects over to U.S. Immigration and Customs Enforcement’s Homeland Security Investigations.
