A female police officer suffered a broken jaw after being kicked in the face by a woman in Taupo yesterday.
The officer and two male colleagues were called to a report of a male assaulting a female about 3.45am.
Taupo Area Commander Inspector Steve Bullock said the woman tried to intervene as the man was being arrested.
"The female officer was verbally and physically assaulted as she attempted to hold the woman back," he said. "Despite having sustained a serious injury, she still managed to arrest the female offender."
The man has been charged with obstruction and assaulting a female, while the woman has been charged with injures with intent to injure.
