A supply teacher has resigned after reportedly taping a child's mouth shut at Fowlmere Primary School, Cambridgeshire, earlier this month.
The act was apparently meant as a joke, but one parent, who didn't wish to be named, told South West News Service: "It doesn't matter whether it was a joke or not." The charity Kidscape described the act as "a form of child abuse".
The school has apologised to the pupil's parents.
A Cambridgeshire council spokesman told MailOnline:
Although there was no ill intent or unkindness intended, it is clear this incident should not have happened and the member of staff has resigned from their post. We have spoken to the child's parents and apologised as this fell below the standards we expect.
A former school governor told the Cambridge Evening News:
I have every confidence that the people in charge at Fowlmere Primary, the headteacher and the governors, have done whatever was needed to be done and have handled this properly. The teacher has resigned and I would think there is really no further need for any parent to be concerned.
