A fire early Sunday at a Des Moines apartment complex left one resident severely injured and displaced several others, police said.

A caller reported smoke in the hallways of 6010 Creston Ave. in the River Oaks Apartments, a little over a mile south of Valley Junction on the Racoon River, about 12:30 a.m. When police and firefighters arrived, a tenant directed them to a first-floor apartment that appeared to be the source of the smoke, Des Moines police spokesman Sgt. Paul Parizek said in a news release.

The release said the tenant had attempted to enter the apartment in search of the 65-year-old man who lived there but was driven back by the fire. It said firefighters located the man and evacuated him via a bedroom window.

He was taken to a hospital, where he was listed in critical condition. The release said firefighters also were able to rescue a pet from the apartment, which was determined to be the source of the fire.

Firefighters extinguished the fire and Polk County Emergency Management was assisting residents displaced by the damage, the release said.

It said the fire remained under investigation later Sunday.
