This is Southwood Primary School where the tragedy took place
Around 40 people were inside Southwood Primary School's sports hall, in Milton Keynes, when the ceiling caved in.
Police and ambulance crews raced to the scene as two children lay injured – one girl is currently in a life threatening condition.
Acting Superintendent Vince Grey said: "Our priority is the two children who have been injured by the collapse of the ceiling.
"South Central Ambulance Service NHS Foundation Trust (SCAS) was called to the scene and treated one child who had minor injuries.
"Thankfully, the child did not require treatment at hospital.
"Another child was assessed and treated at the scene by SCAS for life-threatening injuries and was transported to hospital.
"Our thoughts are with the child and their family at this extremely difficult time.

"It is possible that the collapse of the ceiling was caused by the adverse weather conditions that the country has been experiencing overnight and into today.
