Brookfield School students and staff had to evacuate yesterday after another bomb threat - the second in two days.
Principal Robert Hyndman said the second phone call came to the school reception about 12.28pm, a couple of minutes earlier than the day before.
On Wednesday the caller claimed a bomb had been planted at the school and there was not much time to evacuate.
Mr Hyndman said the first caller also mentioned flying shrapnel.
"Yesterday's call was much the same as the robotic computerised call we received on Wednesday."
