Zach Fogerson, a former Washington football player, is being held in connection with a robbery on the UW campus Monday night.

An 18-year-old student walking through campus was robbed at gunpoint around 10:30 p.m. Monday, according to UW police. Fogerson, 20, of Kent, was arrested by UW police shortly after the robbery.

According to a statement of probable cause, UW police stopped Fogerson as he was driving off campus in a car with its headlights turned off. A silver revolver and the student’s purse and wallet were found in the car, according to King County prosecutors.

He is being held in lieu of $100,000 bail, but has not been charged.

Fogerson left the team in July 2011, after coach Steve Sarkisian said he was suffering from continuing issues with a concussion he received that spring.

Fogerson is the younger brother of another former UW player, Johri Fogerson. Johri Fogerson left the UW program before the 2012 season and played last fall for Central Washington. He was dismissed from the Central Washington team after being charged with third-degree assault.

Both Fogersons attended O’Dea High School.
