A six-year-old boy reportedly took two blades including a seven-inch steak knife to school and threatened to chop off his teacher’s head.
The pupil who was described as somebody “normally quiet” was excluded but because of the incident, he is now back and being taught in isolation.
One shocked mum said: “My daughter said he came to class with a spoon and the two knives.
“This isn’t the Bronx. It shouldn’t be happening.
“He is being given one-to-one teaching but he shouldn’t be allowed back.
“I don’t want a call saying my daughter’s been stabbed.”
Local councillor Dawn Barnetts said: “Some parents are telling me they don’t want to send children back to school.”
But Emma Lake, head teacher at Hangleton Infant and Junior School in Hove, East Sussex, said: “We would like to reassure parents that their children were not put at risk by the incident which was dealt with effectively and immediately by the class teacher.
“Arrangements have already been made to ensure that there is no repetition of the incident, and that the school continues to provide a very safe learning environment for our children.”
