A formal complaint has been laid against a female student at Tangaroa College after she attacked a fellow footballer shortly after an inter-school match.
The student was part of a squad who turned out for a soccer match against Epsom Girls' Grammar junior girls B team. Most of the players are in Year 9 and 10 and are aged from 13 to 15 years old.
The match was played at Tangaroa College, in Otara, on Wednesday.
A parent whose daughter played for the Epsom side and who was at the match said several people - including the players, parents, school staff and spectators - saw the incident unfold.
The woman, who did not want to be named, said the match had just ended and Epsom had won 4-0.
