Multiple police cars and ambulances were reported racing up Westlake Avenue late at night toward the waterfront stretch near the old China Harbor building.

People near the scene described an injured man on the sidewalk with a large amount of blood visible before medics arrived. The response appeared to center on the area immediately next to the old China Harbor building, where an event was underway and people were still gathered outside.

Early accounts circulating overnight described the incident as a stabbing, with the victim and suspect believed to have known each other. One account said the suspect left in a car, but the exact sequence of events was still unclear.

There were also reports of loud popping sounds across South Lake Union, Lower Queen Anne and Capitol Hill around the same time, though those were described separately as fireworks and do not appear to explain the emergency response on Westlake.

Westlake is a narrow, busy corridor where a major emergency response can quickly snarl movement for buses, drivers and people on foot, especially late at night between South Lake Union and downtown.
