A 16-year-old has been charged in connection with a bottle attack at the Christmas in the Park event in Christchurch.
The event at Hagley Park in November descended into violence in the final hour when there was an influx of drunken young people.
A teenage boy was stabbed multiple times, including three times in the face.
The accused has been charged with wounding with intent to injure.
He will appear in the Christchurch Youth Court on Friday.
Police say they are still investigating an assault on an officer at the event.
