A schoolboy has described the moment a teacher was alleged to have tape over her pupils' mouths.
Student Ryan Knowles claimed his teacher had told him and his classmates to stand in a line while she applied the tape to keep them quiet.
Furious parents are now calling for the teacher to be sacked, with one mother saying she was "disgusted" and a father claiming the incident caused his daughter's lips to bleed.
