A five-year-old suffered a broken collarbone after she was hit by a falling fire door at school.
The child was left lying injured for around 90 minutes after a fire door was said to have fallen on her at Stag Lane Primary School near Burnt Oak.
The incident happened at around 2.30pm on Monday (June 28), but despite an ambulance being called immediately, it took an hour and a half for a paramedic to arrive.
During this time, the girl was left in pain on the floor being cared for by teaching staff.
The girl’s uncle, Cristian Silaghi, said: "The mum is heartbroken and she can’t sleep. (My niece) is recovering but she has a broken collarbone. She was lying on the floor all this time.
"The school haven’t said how it happened, just that they are investigating it. We’ve got pictures of the broken hinges. We want to know how and why this happened. The school needs to prove it is safe."
The girl’s distressed family claim the door that fell was in a state of disrepair and they have also questioned why it took so long for an ambulance to arrive.
When a work colleague of the girl’s father arrived at the school and inspected the hinges on the door, he said it looked like what happened had been "a long time coming".
The red door was a part of a double door that leads out onto the school playground.
Harrow Council has confirmed an investigation has been launched to find out how and why the door came to fall off.
Stag Lane Primary School directed the Times to Harrow Council when approached about the incident.
A council spokesperson said: "This was a distressing incident and our thoughts are with the injured party, whom we understand will make a speedy recovery.
"An investigation is ongoing to discover the cause and our safety protocols are subject to regular review. We await the findings of this investigation with interest and will implement any necessary recommendations.
"An ambulance was called immediately after the alarm was raised and a number of subsequent calls were placed with emergency services to ascertain its whereabouts.
"We are unable to comment further until the investigation is concluded."
The London Ambulance Service (LAS) has confirmed it received its first call to the school in Collier Drive at 2.31pm on Monday, and received another call at 2.51pm.
Paramedics eventually arrived at the school at 4.03pm and the girl was treated and taken to hospital.
An LAS spokesperson said: "We're very sorry for the delay in reaching this patient and any distress that this may have caused. Our Service is very busy at the moment, and on 28 June we received more than 6,500 calls into our 999-control rooms, compared with a usual ‘busy’ day of about 5,500 calls.
"We aim to get to all of our patients as quickly as we can but must prioritise reaching those who are most critically ill and injured, such as those who have stopped breathing or are suffering cardiac arrest. All callers are given clear advice about ringing 999 again if the condition of the patient changes."
