Hawke's Bay's top police officer says the violence her officers are experiencing is "unacceptable" after a female police constable was attacked in Napier.
The officer was struck with a pair of vice grips during an arrest in relation to a stolen vehicle on Saturday morning.
The constable, allegedly struck by an associate of the person being arrested, received two stitches and a concussion. She is currently off work and recovering at home, police said.
A youth appeared in the Youth Court in Hastings on Monday and was due to reappear later this week.
Eastern District Commander Tania Kura said violence towards police staff is unacceptable.
