Three police officers have been stood down after allegations of excessive force used against a 16-year-old boy.
West Australian Police's internal affairs unit are investigating the incident at the Halls Creek Police Station in the Kimberley, which has seen one 25-year-old constable charged with assault occasioning bodily harm.
It will be alleged the teenaged detainee was pulled to the ground, and was then injured while being transferred from the pod of the police vehicle to the lock up.
The youth allegedly received a cut to the side of his face which required medical attention.
The conduct of two other officers during the incident last November is also the subject of an internal investigation.
All three officers have been stood aside from operational duties.
The officer charged with assault will appear in the Halls Creek Magistrates Court on February 5.
