The shooting took place around 10 p.m. Sunday, police said, when demonstrators were marching from the CHOP to downtown Seattle. The teen was taken to a Harborview Medical Center with a gunshot wound to the arm, police said, but he declined to speak with investigators.
He was released from the hospital after treatment.
There were reports of a second victim, but police were unable to confirm if it was true.
Sunday’s incident is the second consecutive day a shooting was reported in or near the CHOP. A 19-year-old man was fatally shot Saturday and another sustained life-threatening injuries, police said. The suspect remains at large.
