Ben Moen, left, Charles Atwell and Cody Moen clean graffiti off of a bus stop in downtown Auburn on Saturday morning. Forty students and five off-duty Auburn Police officers joined forces during the second annual Graffiti Cleanup, said Ben and Cody’s father, Deputy Chief Jason Moen. Walls, signs, electric boxes and baseball dugouts were scrubbed and some painted during the event that lasted from 9 a.m. till noon. Following the cleansing, volunteers from the Edward Little High School crosscountry track team, students from the law enforcement program at the Lewiston Regional Technical Center and children of the participating officers were treated to a pizza party at the Auburn Police Department. Ben, 10, and Cody Moen, 12, live in Casco. Atwell is a 15-year-old freshman at Edward Little.
