A teacher who was one of three people stabbed by a Hitler-obsessed teenage pupil has said she ‘can’t imagine’ going into a school ever again and ‘could never’ return to work.

Liz Hopkin, 54, also told how there ‘isn’t enough action’ to tackle the problem of knives being brought into schools or to keep staff and children safe, adding: ‘The incidents that are happening are the tip of the iceberg.’

She was attacked when she intervened as the assailant lunged at one of her colleagues, Fiona Elias, yelling: ‘I’m going to kill you’.

She gabbed the knife-wielding teenager but then found herself on the receiving end of a vicious attack.

Ms Hopkin said: ‘She stabbed me in the leg and then she came towards me and stabbed me in the neck and then twice in the back.’
