The driver of a car who crashed into a Wimbledon school and killed two eight-year-old girls suffered an epileptic seizure behind the wheel.
Claire Freemantle will face no criminal charges following the collision at The Study Prep school in south-west London, on July 6 last year.
Pupils Nuria Sajjad and Selena Lau died after the 4×4 crashed through a fence and hit a building.
In a joint statement, the girls’ families said: "We remain unconvinced that the investigation has been conducted thoroughly.

"Nuria and Selena deserved better."
Freemantle had never had an epileptic seizure and was in good health, prosecutors said.
The driver expressed her "deepest sorrow" and said she had "no recollection of what took place” after losing consciousness.

She said: "Since I became aware of the terrible event that took place on July 6, the devastating consequences for all those affected have not left my thoughts and will be with me for the rest of my life.
"I have since been diagnosed as having suffered an epileptic seizure with loss of consciousness. This was not a pre-existing condition. As a result of losing consciousness I have no recollection of what took place.
"I can only express my deepest sorrow for the families who have suffered such dreadful loss and injury.
"As a mother, I understand there can be no words that adequately express the pain and loss resulting from what happened in those horrendous moments while I was unconscious."

Nuria and Selena’s families had previously expressed frustration at how long the investigation into the crash was taking, exacerbated by a lack of specialist forensic collision investigators.
Metropolitan Detective Chief Superintendent Clair Kelland said that having examined her medical records, the driver could not have predicted or prevented the seizure.
She said: “I can understand that some may be confused – perhaps even feel let down – by this outcome and want to give every reassurance that our officers worked tirelessly through every detail of the incident to ensure a complete investigation be passed to the CPS.
“To bring charges in cases like this there needs to be an element of responsibility on the part of the driver, and, given the circumstances, this was simply not borne out on this occasion.”
