The teenager who seriously injured "Good Samaritan" Lucy Knight during a violent bag snatch committed a similar robbery only five days earlier.
Hendrix Hauwai, 17, was due to be sentenced yesterday on two counts of assault with intent to rob and causing grievous bodily harm to facilitate his flight from the scene after the incident outside a North Shore supermarket on September 23.
But the hearing was adjourned because of extra charges of robbery and assault with intent to injure coming from Manukau District Court.
Hauwai had no assigned legal counsel on those counts but that was remedied later yesterday afternoon at North Shore District Court.
Defence counsel Kelly-Ann Stoikoff went through the police allegations with her client and gave guilty pleas on his behalf.
