An Acorn RISC computer, a Microvito monitor and printer used to teach children literacy and numeracy skills were stolen from a temporary classroom at Maple Infants School overnight between May 10 and May 11.

School head Jean Cutts said all computer equipment was now being stored in an alarmed area.

"It is pretty sad that they had obviously cased the classrooms in advance and had come prepared," she said.

"Someone has planned this and they have stolen from very young children."
