U.S.  Border Patrol spokesman Eric Dorais said that at around 9:10 a.m. PT, U.S. border agents encountered two men wearing camouflage clothing and backpacks in the Columbia Valley area, approximately 12 kilometres east of the Huntingdon/Sumas border crossing.

"One of the subjects fired at the agents and fled into the woods," Dorais said in a written statement.

The other individual was taken into custody, he said. No injuries were reported.

Abbotsford police Const. Ian MacDonald says his department was then notified that the second suspect may have fled toward Canada.
