The incident began at about 9:40 p.m. when police responded to multiple 911 calls about two groups of people shooting at each other near 3rd Avenue and Lenora Street, said Seattle police spokesman Jeff Kappel.
When they arrived, responding officers on scene, they were unable to locate any suspects or victims after an extensive area search.
Then, about 45 minutes after the initial calls, someone called 911 to report a man with a gunshot wound getting on a Metro bus at 3rd Avenue and Pine Street.
Police quickly found the bus and pulled it over at 3rd Avenue and Union Street. Officers boarded the bus and found a male in his 40s with a gunshot wound to his abdomen.
Medics responded to the scene and transported the victim to Harborview Medical Center with non-life-threatening injuries.
The victim was not cooperative with officers and would not say what led up to the shooting, nor would the victim provide any information about suspects, Kappel said.
A preliminary investigation has not yet determined whether there was one shooter or more. The investigation continues.
