A four-year-old boy who was killed by a car that crashed into him and two adults outside a medical centre in Melbourne's east had been holding his dad’s hand at the time of the crash.
Witnesses said the out-of-control Toyota LandCruiser crossed the median strip onto the wrong side of the road before becoming airborne and taking out at least 10 vehicles.
The 4WD struck the four-year-old boy waiting with his dad in the car park of the Epworth Specialist Centre on Kangan Drive in Berwick, just before midday.
Bystanders and medical staff rushed to perform CPR on the boy but his injuries were too horrific.
“As he’d come over the median strip, up over the grass, he was going faster and faster,” Amy Murchie, a witness, told 9NEWS.
Police confirmed the Narre Warren south family was visiting the medical centre and the boy’s father was holding his hand at the time of the crash.
“I remember the dad [of the boy] saying ‘it’s my fault’. It’s not his fault,” witness Sarah Smith said through tears.
Cameron and Sarah Smith were driving behind the LandCruiser when the crash happened and rushed to assist.
"He was in front of us and he started to veer off into oncoming traffic and he's gone airborne," Mr Smith said.
"He stated that he had dialysis, he just had blood taken out and he just literally pulled (out) from the hospital."
Aaron Kishere, another witness, said the driver of the LandCruiser was only two metres away from hitting his son.
“He was very close. I don’t know how he missed us,” Mr Kishere said.
A woman in her 60s suffered minor injuries from the crash and was taken to Casey hospital.
She is not related to the boy.
Aerial photographs of the crash show a number of damaged parked cars, that appear to have been pushed by the Toyota LandCruiser which flipped onto its side.
The driver of the 4WD is being treated at Dandenong hospital and is cooperating with police as they investigate the cause of the crash.
Anyone with further information is urged to contact Crime Stoppers on 1800 333 000.
