Dominque Ormsby landed a coward punch to the back of a senior policeman's head during a riot in Ōtangarei in which police cars were damaged and a number of people were peppersprayed.
The officer stumbled but continued with his duties while Ormsby ran off and tried to hide in the crowd outside a house on the corner of William Jones Dr and Matai St, in the Whangārei suburb of Ōtangarei, on March 9 this year after an alleged family violence incident about 9.45am.
When police arrived a male was found with a stab wound and transported to hospital in a serious condition.
At the time a neighbour described seeing young people going crazy and screaming and yelling. "They had softball bats and wooden poles like battens. I think they were yelling at the young fella in the house,'' the resident said.
"Police had the whole place blocked off. It was a full-on riot."
