New technologies constantly test school policies around cyber safety, a Whangarei principal says, following the posting of a video on to Facebook and YouTube which showed a student 14, being beaten up by classmates at Ruawai College near Dargaville.
Police are investigating two separate incidents of cyber bullying after videos of students fighting were posted on social media sites.
"It's a trend that's happening in schools and it's quite scary for us because we're very aware of the kinds of things that can occur," Whangarei Intermediate principal Hayley Read said.
The student was attacked in the school bathrooms while a group of other students looked on and filmed.
Two students, aged 15 and 16, have been thrown out of the college and face charges in the Youth Court. Two younger students have been referred to Police Youth Aid.
