Central Washington Hospital in Wenatchee was closed to the public much of Sunday and reopened Monday morning with “significant security” after a man was brought in with multiple stab wounds in what police say was a gang-related attack.

Wenatchee Police Sgt. Cherie Smith said hospital personnel asked police to search the hospital Sunday after someone forced open a locked door at the hospital during the lockdown. It was thought that one of the man’s attackers may have been inside.

An 18-year-old Wenatchee man was in stable condition at the hospital, according to a nursing supervisor. Kruse said the victim suffered a collapsed lung and a stab wound to the stomach.

Rivercom Dispatch received a 911 call around 1 p.m. Sunday to report a man covered in blood near the intersection of Franklin and Idaho streets. Witnesses reported seeing a man being chased northbound on Franklin by two other men, estimated to be in their late teens or early 20s. One witness “thought they were playing around until she saw blood on the victim and realized that he had been stabbed.” The two suspects then ran away on foot.

The victim would not give any information to police however he told witnesses who tried to help him before police arrived that he was attacked by two rival gang members.
