BLAINE, Wash. (AP) — Customs and Border Protection officials say officers arrested three Mexican men as they crossed into the U.S. from Canada on a freight train carrying grain.

Agency spokesperson Renne Archer says the men ranging in age from 25 to 33 were arrested Sunday.

She says they were hiding in a rail car under garbage bags.

Archer says the men were processed for removal from the United States and then taken to the federal government’s privately-run Northwest Detention Center in Tacoma.
