PORTLAND, Ore. (AP) — An Oregon teenager who escaped from a youth prison last month is back behind bars.

State police say 18-year-old Micah West was arrested late Tuesday after he was caught shoplifting candy bars in Albany. He's been lodged at a juvenile detention center.

West and 18-year-old Brittain McAuliffe vanished from Camp Riverbend, a transitional living facility in La Grande. Authorities say they left through a gate June 20 after taking a slide card.

Police believe they later stole a pickup from the Emigrant Springs State Heritage Area.

McAuliffe is still free. He was spotted days after his disappearance at a pharmacy in Milton-Freewater.

The escape was the first at Camp Riverbend since 2008.
