U.S. Customs and Border Protection field operatives seized 266 pounds of cocaine last week from a tractor-trailer entering the country outbound from Canada, the agency revealed Tuesday. Alerted by K-9s, CPB field operatives found 100 bricks of narcotics stacked behind a false wall in the trailer trying to cross at the Blue Water Bridge port of entry. Agents arrested the driver, a Canadian citizen, once testing confirmed the drugs were cocaine.
