A major emergency response was triggered in Wimbledon, southwest London, after a car plowed into the private Study Prep girls' school, leaving one girl killed and several children injured on Thursday 

The incident was not being treated by police as terror-related as the driver, a woman in her 40s, did not leave the scene and was arrested. 

London's Metropolitan Police confirmed the death of the child and that the driver is now detained on suspicion of causing death by dangerous driving.

It was stated earlier that seven children and two adults were injured while a member of parliament said he was informed that several injuries were "being treated as critical."

MP Stephen Hammond called the crash "extraordinarily distressing and tragic." According to the school's website, Thursday was the last day of school for students aged four to eight.

Aerial footage taken of the scene, which lies not far from the Wimbledon tennis tournament, shows a Land Rover car stopped against the wall of the school building and in an area close to colored play mats.

Ambulance, fire service, and police were called to the scene just before 10 am (0900 GMT), as witnesses and reporters stated that the road outside the school was narrow, indicating difficulty to be able to build up speed.

The Study Prep school hosts girls from aged four to 11 with the youngest students taught near the Royal Wimbledon Golf Club.

Health Minister Steve Barclay said, "My thoughts are with those sadly injured and everyone who has been affected," while London Mayor Sadiq Khan called it "absolutely devastating".
