On Tuesday a police officer from Ralston Nebraska was at the Southwest Iowa Law Enforcement Training Facility in Council Bluffs to do some training.

The officer was using a stun gun for an exercise when he shot himself in the hand with the device.

Council Bluffs Police Sgt. Greg Schultz says the officer fired his stun gun once and was trying to reload another cartridge into it when the stun gun discharged. A probe from the weapon stuck the officer’s left hand where the pinky meets the hand.

The officer’s name was not released. The officer lost feeling in his finger and was taken to a hospital.
