A teenager has been charged after allegedly saying "this teacher is mean as f***" in a public place.
The 17-year-old Lower Hutt boy is charged with using indecent language within hearing of Hutt Valley High School on October 27.
He is also charged with trespassing at the school on the same day, according to a charge sheet seen by the Herald at Hutt Valley District Court.
Hutt Valley High School principal Ross Sinclair was unsure of the exact incident involving the 17-year-old accused of swearing, but said there had been incidents recently where groups of people had come onto school grounds and refused to leave.
He said the people had been "resistant" to staff trespassing them from the grounds and had used rude language to them.
