Today's police update in full
"Detectives continue to investigate a collision at a school in Wimbledon.
"Police were called at 09:54hrs on Thursday, 6 July to reports that a car had crashed through a fence and collided with a building at The Study Prep School in Camp Road, SW19.
"A total of 35 police vehicles were deployed to the scene and officers worked with paramedics to give first aid to a number of people who had been injured.
"Sadly, despite the efforts of the emergency services, an eight-year-old girl died at the scene.
"Her parents are being supported by family liaison officers and our thoughts are with them at this time.
"A second eight-year-old girl was taken to hospital where she remains in a life-threatening condition. Her family have been informed and are also being supported.
"A woman, in her 40s, also remains in hospital in a critical condition.
"A number of other people – including a seven-month-old girl - were also taken to hospital and their conditions have been assessed as not life-threatening.
"We understand the school-age children were pupils at the school. The injured adults were parents/carers of the children; not staff members.
"The driver of the car, a 46-year-old woman from Wimbledon, was arrested at the scene on suspicion of causing death by dangerous driving.
"She was taken to hospital - her condition was assessed as not life-threatening. She has been bailed pending further enquiries to a date in late July.
"Detectives from the Met's Serious Collision Investigation Unit are leading the investigation and their enquiries are ongoing. They are expected to remain at the scene throughout the day.
"The investigation remains in its early stages and officers are keeping an open mind whilst following up all lines of enquiry. We ask that people do not speculate about the circumstances while this work is ongoing."
