“She tried to stab one of my best friends and attacked a little kid,” she said.
Two 13-year-old Dunedin North Intermediate School pupils said the woman had thrown a cigarette at them and told them they should start smoking.
One of the pupils said the woman told him he should date her 21-year-old daughter.
The incident left him “weirded out”, the pupil said, and the two of them went inside the nearby McDonald’s restaurant to get away from her.
OGHS pupil Kaitlyn Sim (14) said she had been at the centre of the altercation.
“She pulled the knife in front of my face, I tried to grab it. She shoved me, I pushed her back,” she said.
The woman had also talked about wanting to blow people up. The knife was a bread knife, but it had been serrated and sharp, Sim said.
Another OGHS pupil, Claire Bevin (14), said the woman had also been asking random passersby if they had a gun.
