A 31-year-old North Bend man was treated for stab wounds, reportedly inflicted by his 30-year-old brother Monday afternoon in a parking lot in the 42900 block of Southeast North Bend Way.

A witness called police at 1:10 p.m. to report the incident. The two brothers had been arguing when the younger one pulled out a folding knife and slashed the older brother, leaving a six-inch-long cut in the victim’s chest.

King County Sheriff’s Deputies throughout the Snoqualmie Valley responded to the call within three minutes, and began processing the crime scene. Eastside Fire & Rescue treated the victim on-site and transported him to Overlake Hospital.

The seven deputies on the scene interviewed witnesses and tracked the suspect to a heavily wooded area about 200 yards from the crime scene. The man was arrested and booked into the King County Jail for assault, first degree. Bail has not been set.

The Sheriff’s Office Major Crimes Unit will refer charges to the King County Prosecutor’s Office.
