PIERRE, S.D. (AP) — The Pierre Police Department will examine its policy for the use of stun guns in the wake of an incident in which an officer used a stun gun on an 8-year-old girl.

Chief Bob Grandpre tells the Capital Journal that officials with the Rapid City Police Department and the state Highway Patrol have been asked to help with the review. He doesn't have a specific time estimate but says once the group is assembled the review of the three-year-old policy shouldn't take long.

The state attorney general's office is investigating whether the unnamed officer acted appropriately when he used his stun gun on the girl Oct. 4. A Pierre Police Department review earlier concluded that the officer acted appropriately because the girl was suicidal and turned a knife toward the officer.
