THE driver at the centre of the Wimbledon school horror may have had a seizure before the crash.
A source said the woman, 46, was found to be “delirious” after the incident which killed an eight-year-old girl — and had bitten through her own tongue.
Police believe it supports the theory she had a medical episode before her Land Rover careered through fencing and into The Study Prep School.
Teachers, parents and children scattered when the 2½-ton Land Rover 4×4 shot across the lawn towards them during an end-of-term tea party.
The car hit Selena Lau, who died at the scene, and left another girl of eight and a woman in her 40s critical.
Sixteen people were hurt in Thursday’s 10am crash including a seven-month-old girl — the sister of a pupil at the South West London private school.
The £70,000 Defender 110 model drove through them before smashing into a wall.
One source said: “The driver was in a delirious condition and had bitten through her tongue.
“She’d stopped outside the school but the car took off as if the driver had suddenly floored the accelerator.
“At this point the police believe she had some kind of seizure just before the accident.”
The driver, who lives locally, was held on suspicion of causing death by dangerous driving.
She was treated in hospital before spending a night in police custody and was then bailed pending inquiries.
It was understood she was not over the alcohol or drug limit.
The Met’s Serious Collision Investigation Unit is looking into her medical background.
A spokesman said: “The investigation is in its early stages and our officers are keeping an open mind.”
