THE alleged driver of a car that crashed through a classroom wall, killing two young boys, has been slapped with further charges over the other children injured in the incident.

Maha Al-Shennag, 52, was charged with two counts of dangerous driving occasioning death, driving in a dangerous manner and negligent driving occasioning death, after the Toyota Kluger she was driving slammed into a year three classroom at Banksia Road Primary School in Sydney’s south-west on Tuesday.

After further investigations, police on Thursday morning announced she had been hit with extra charges relating to children who survived the incident but sustained injuries and were taken to hospital.

“Yesterday, following investigations, the driver was additionally charged with dangerous driving occasioning grievous bodily harm and cause actual bodily harm,” police said.

“Police will allege the additional charges relate to injuries sustained by children who were taken to hospital.”

Two boy, both aged eight, were critically injured in the horror crash and were taken to The Children’s Hospital at Westmead where they were pronounced dead.

Two eight-year-old girls were taken to the same hospital in a stable condition, and another girl, aged nine, was taken to hospital in a serious condition.

Ms Al-Shennag was taken to Bankstown Hospital for mandatory blood and urine testing after the crash, but was uninjured.

Her licence has been suspended and she was granted conditional bail and is due to face Bankstown Local Court on Wednesday, November 29.

Earlier, a family member of one of the students seriously injured in the crash told news.com.au she still hadn’t been told her classmates had died.

The relative said the girl had been in pain all night — but it was the emotional scars her loved ones feared the most.

“She still doesn’t know her classmates passed away. She keeps asking about them,” the relative said.

The family is delaying telling her the tragic news until she is stronger.

The injured eight-year-old had not slept much overnight due to the pain she was in and also due to the trauma she’d been through.

“She just had stomach and chest pain all night and didn’t sleep well due to what happened — she’s very frightened.”

There were 24 children aged between seven and 11 in the year three classroom at the time the car crashed through the wall.

Police have said they believe the driver may have become distracted by something moments before the fatal crash in Greenacre.

It’s understood one line of inquiry for crash investigators is that a stray water bottle may have distracted Ms Al-Shennag.

It’s believed the mother-of-four may have dropped the water bottle and accidentally put her foot on to the accelerator, sending the SUV hurtling into the demountable building where children were learning.

They will also closely examine her mobile phone and the wrecked Toyota Kluger for clues.

A police spokeswoman would not comment on the claims as the case was now before the courts.

After her arrest, her lawyer Nick Hanna said his client was “deeply sorry for the loss and hurt suffered by the children, the school, the families and the community”.

He added: “Her thoughts and prayers are with all those affected.”

It is understood the mother-of-four’s husband died earlier this year.

One of her neighbours told The Daily Telegraph: “She was so kind to us when we moved in — she bought us food and welcomed us to the street. She’s always so nice to everyone around her.”

The school has been open and in operation since the crash, but only a fraction of its students have been in attendance.

The school gates have become a makeshift memorial for the boys killed in the crash, with children leaving flowers and cards in tribute for their lost schoolmates.

“May Allah bless you, both will be missed always,” one message said. “A good heart has stopped beating, a good soul has ascended to heaven,” said another.

“God is with you fly high into heaven,” one card said that was surrounded by flowers and soft toys.
