WARNING, DISTRESSING CONTENT: New footage has emerged of the moment a car crashed into pedestrians in Melbourne's CBD which left 17 people in hospital.
The shocking CCTV footage from Flinders Street shows how bystanders rushed to the aid of the injured, who were strewn across the road after the horror incident, which occurred shortly after 4.30pm on Thursday.
Exclusive security video obtained by 7 News shows the moment the Suzuki Grand Vitara pauses for seven seconds before deciding to veer into the central tramway, narrowly avoiding a man in an orange shirt as he sped towards unwitting pedestrians.
The footage shows some people fleeing, others jumping into action and rushing to the aid of the fallen. One off-duty police officer managed to drag the culprit from the vehicle.
"He's nothing short of an absolute hero," Victoria Premier Daniel Andrews said of the officer on Friday.
One victim, 17, managed to push a friend out of the way of the onrushing car but his selflessness resulted in being clipped by the vehicle himself.
"I was just like mid-air, the car just came across and whacked by right ankle," Ethan recalled.
Witnesses revealed the shocking nature of the attack, suggesting the vehicle was travelling at around 100km/h.
"The only thing that slowed him down was him hitting pedestrians," witness Jim told ABC TV of Thursday's incident.
Seventeen people were injured on the street including nine from overseas. The youngest victim was a four-year-old boy, while the oldest was an 83-year-old male.
He remains in a critical condition while the young boy has head injuries.
The alleged driver of the white 4WD was Saeed Noori, a 32-year-old Afghani-Australian.
