The driver of a car that crashed into a school killing two eight-year-old girls will face no criminal charges after it was found she had suffered an epileptic seizure behind the wheel.

Nuria Sajjad and fellow eight-year-old pupil Selena Lau died after the crash at The Study Prep school in Wimbledon, south-west London, on July 6 last year.

Several others were injured when the 4×4 crashed through a fence and collided with a building.

Trevor Sterling, lawyer for the families, said: “This is disappointing; justice must not only be done, but seen to be done.

“In the absence of a process, how do we interrogate the evidence? What does this message send to the public that deaths can arise in a road traffic situation, and there could be no sanction because there is no process to interrogate the evidence?

“The next focus will be on the inquest, and there will be a deep and thorough review of the evidence, which will be examined by a jury if necessary.”
