FIREFIGHTERS, police and paramedics were called to Hazeley School at 1pm today after an explosion in the science laboratory.
At least one member of staff was injured and taken to Milton Keynes hospital.
The school – an academy which specialises in science – was closed for the day due to teachers taking part in the national strike action.
But it is understood non-striking staff had gone in to the lab to make preparations for a science exam due to take place later this week.
Witnesses have spoken of children also being in the school but it is believed these could have been the children of staff members.
“It looked really dramatic,” said one witness. “I saw fire engines, helicopters, ambulances and police all arriving at once. We couldn’t understand what was happening because the school was meant to be closed.”
A spokesman for the school said: “There has been an isolated incident in The Hazeley Academy which was dealt with by the emergency services.
“All Academy children are accounted for and safe. A member of staff was taken to hospital and we will report later as to any possible disruption to the school day tomorrow.”
More to follow shortly.
