WICHITA, Kan. (AP) -- A Wichita police officer is on administrative leave after firing at a man who appeared to aim a weapon at him.

No one was injured in the shooting overnight Tuesday.

Police say the officer was working on paperwork in a parking lot when he saw someone looking around the corner of a nearby building. The man went away and returned a few minutes later.

Police say the officer got out of the car and began firing after it appeared that the man aimed a rifle at him. The man ran away and police say it's not clear if he was hit by any of the officer's shots.

No one has been arrested.
