Police wrongly handcuffed and arrested an innocent man who was then bitten by a police dog, the Independent Police Conduct Authority has found.
However neither officers would be prosecuted over the incident which happened in Upper Hutt on January 23 last year.
The innocent man was taken from his home by a police sergeant and dog handler who went to the property in search of another man who had threatened his ex-partner and rammed her car.
The woman was the daughter of the victim and he answered the door when police arrived.
He was immediately arrested and handcuffed by the sergeant although the officer did not match him to the description of the offender.
As the dog handler assisted the sergeant with escorting the father down the driveway, his police dog bit the man without being commanded to do so.
