FRESNO, Calif. (KSEE/KGPE) — Authorities say a K9 officer was stabbed multiple times while responding to a 911 call Saturday morning.

Around 11:30 a.m., Fresno Police received a call regarding a woman who was being held against her will at a home on West Brown Avenue, near Hughes Avenue.

When officers arrived at the home, they met a man at the front door, believed to be the suspect. The man, Carlos Castanos, ran off through the back door of the home and jumped over the back fence, where K9 Officer Argo was waiting with his handler.

The officer asked Castanos multiple times to comply, but the man refused, so they unleashed the K9 on him.

Police say Castanos pulled out a large box cutter and stabbed K9 Argo in the back and the left eye.

While the officer was trying to get the suspect to comply, a pit bull came out from the yard and began attacking Argo, before going after his handler.

The officer fired one round from his gun and hit the pitbull one time as Castanos continued to stab Argo. Argo was stabbed six times and was taken to an emergency vet on McKinley Avenue for treatment, where he is listed in stable condition.

Officers were able to take the suspect into custody after tasing him.

Police believe the K9 officer might have been killed during this incident, and have credited Argo with saving his life.
