I saw this pop up on the 911 website this morning at 5:45 and just got some details of what happened. Evidently police responded to a report of a man with a knife chasing another man in his underwear at the intersection of 20th Ave and E. Columbia.
The victim in the assault was found with multiple stab wounds and taken to Harborview. A suspect in the stabbing was taken into custody.
Let us know in the comments if you saw this happen or have any more information.
