Eleven pupils in Kent were injured, two seriously, when a school heating duct collapsed last week as they sat an exam. The Year 9 students were in a sports hall at Minster College on the Isle of Sheppey when part of the ceiling collapsed. Ambulance crews were called shortly after 9am and the school was closed for the day. An ambulance service spokesman said: "We sent 11 vehicles to the scene. They included emergency ambulances, single responder cars and patient transport ambulances. Two of the patients have serious neck, head andor back injuries. The other nine have more minor injuries."
