On July 12th, at approximately 8:15 PM, a physical fight occurred between two men at a mission in the 300 Block of 2nd Avenue Extension South.  One of the men grabbed a knife and chased the other man out into the street.  The suspect then stabbed the victim once.  Officers arrived and arrested the suspect after witnesses pointed him out.  The 31 year old suspect still had the knife in his possession.  He was later booked into the King County Jail for Investigation of Assault.  The victim was treated at the scene by Seattle Fire and then transported to Harborview Medical Center for his non life-threatening injury.
