A 61-year-old man was stabbed in the abdomen Friday afternoon near North 45th Street and Meridian Avenue North in Seattle’s Wallingford neighborhood, according to police.

Seattle Fire Department medics took the wounded man, who was in critical condition, to Harborview Medical Center, said SFD spokesperson Kristin Tinsley.

Police received calls about two men fighting on the sidewalk at 3:54 p.m., according to a Seattle Police Department online blotter post.

Police said witnesses gave them a description of the assailant. A 65-year-old man with a knife was found several blocks away and arrested. He was booked into King County Jail for investigation of first-degree assault. It’s not known whether the man arrested knew the victim.
