U.S. Border Agent Eric Dorais said officers saw two suspected drug smugglers wearing camouflage clothing and carrying backpacks Tuesday on a logging trail about 8 miles from the Sumas, Wash., border crossing with Abbotsford, British Colombia.
When officers tried to make contact with the men, "one of the subjects fired at the agents and fled into the woods," Dorais said in a statement.
Border Patrol officers arrested the other man, The Bellingham (Wash.) Herald reported. They also recovered a backpack at the scene.
Authorities described the shooter as a black man wearing camouflage and a handgun holster, the newspaper said.
Abbotsford police joined the manhunt when they were notified the armed man may have fled toward Canada, the Canadian Broadcasting Corp. reported.
Nearby Upper Sumas Elementary School was locked down, the CBC reported.
