A 14-year-old will appear in court tomorrow over the shooting of a student at Paeroa College this morning.
Police say the alleged shooter was sitting in the class at about 10am when he placed a bandanna over his face, pointed a spring-loaded pellet gun at a classmate and shot him three times in the head and face.
A male teacher was also allegedly shot at as he intervened, and another three or four shots were fired into a wall.
The teacher disarmed the boy and kept him in the classroom until police arrived.
Eastern Waikato area commander Inspector Dana McDonald says a school emergency action plan was put in place.
