(Portland, OR) -- Portland Police continue to coordinate missions to focus on stolen cars. They use specific criteria to stop vehicles that are potentially stolen. In last week's mission, they worked with Gresham Police, Port of Portland Police, Vancouver Police, and the Clackamas County Sheriff's Office. They made 28 traffic stops, recovered eight stolen vehicles and arrested six people. Five drivers tried to elude police and four of them were arrested. Eight vehicles were towed. Deputies from the Snohomish County Sheriff's Office joined the mission to observe the techniques, so they can conduct similar missions in their area.
