Melbourne, Australia (CNN) The driver of a car which plowed into Christmas shoppers in Melbourne Thursday had a history of drug use and mental health issues, police said.
Acting chief commissioner of Victoria Police Shane Patton told reporters that while the crash was considered to be deliberate, there was no evidence of a link to terrorism.
Eighteen people were injured, including at least one young child, when the car hit pedestrians outside Melbourne's iconic Flinders Street station just after 4.40 p.m. local time.

What happened
The streets outside Melbourne's iconic Flinders Street Station was busy with commuters and shoppers Thursday when witnesses said the SUV plowed into people crossing the street.
Witnesses told CNN affiliate Seven Network they saw people flung into the air after being hit by the car, which was barreling down the road at around 60 miles per hour (100 kph).
Police arrived on the scene within 15 seconds and the man was taken into custody by an off-duty police officer after attempting to resist arrest, Patton said. Both the man and the police officer were injured in the scuffle.
A 24-year-old man was also arrested at the scene, after he was seen filming the incident on his phone. Police found three knives in his bag. The man is being interviewed by police but Patton said at this stage, "we don't yet have any relationship established between the 24-year-old man and the driver... in fact, there may be no relationship between them."
The driver was known to Victorian Police due to "historical assault matters" and a history of drug use. "We understand he is on a mental health plan and receiving treatment for a mental illness," Patton said.
People gather at the scene of where a car ran over pedestrians in Flinders Street in Melbourne on December 21, 2017.
Victorian Premier Daniel Andrews called it a "terrible, evil cowardly act," but said there was no need to change the state's threat level. He urged Victorians to go about their business as usual and enjoy the holiday season.
Flinders Street is one of Melbourne's busiest pedestrian roads, running between a major train station and the bustling city center. It would have been crowded with commuters and shoppers making their final purchases in the days before Christmas.
Paramedics took 19 people to nearby hospitals, including the driver. Two others were treated at the scene. Victoria Police spokesman Comm. Russell Barrett told reporters several of those injured were in a critical condition.
Among them was a pre-school age child who was taken to hospital with a head injury, and is in a serious condition, Ambulance Victoria said.

'It just plowed into the crowds'
Jim Stoupas, owner of the Walkers Donut shop on Elizabeth Street, told CNN he saw an SUV going about 60 miles an hour (100 kph) down Flinders Street.
"It just plowed into the crowds," he said. "We heard this noise and we looked up then we just heard bang, bang, bang and people flying everywhere. We had a lot of customers in our shop and they were traumatized."
Another witness, Cameron Von Borstel, said he assumed a car had crashed into a tram when he heard a loud bang from the direction of Flinders Street.

"I went down the street to have a look. I saw about two or three people lying still in the street. People were helping," he told CNN.
Concrete bollards were erected along the side of some Melbourne city roads by the government in June, after a number of vehicle-related terror attacks around the world.
The streets and landmarks around Melbourne's Flinders Street station have been the target of multiple attempted terrorist plots, all foiled by police within the past year.
Less than a month ago, a man was charged with terrorism offenses over a plan to shoot "as many people as he could" on New Years Eve at Federation Square, a large public space beside the station.
In December 2016, Australian police announced they had foiled a plot to blow up improvised explosive devices around Melbourne's city center on Christmas Day , including Flinders Street Station.
It was described as "one of the most substantial terrorist plots that have been disrupted over the last several years."

'Shocking scenes'
Australian Prime Minister Malcolm Turnbull said in a statement his thoughts and prayers were with the victims of the "shocking incident," and pledged federal authorities would work with Victoria's security agencies to investigate.
Everyone in Melbourne would have crossed that intersection at one time or another. As we think about everyone hurt and in hospital, their families and their loved ones, let's not close up with fear but open up with love. — Adam Bandt 🏳️🌈 (@AdamBandt) December 21, 2017
Bill Shorten , leader of the opposition Labor Party, said there were "shocking scenes" coming out of Melbourne. "Credit to first responders who are doing us proud once again," he said. "Thinking of everyone caught up in this atrocity."
The incident comes almost one year after six people were killed when a car plowed into pedestrians along Melbourne's Bourke Street Mall in January, just a few streets north of Flinders Street station. Police said that incident was not terror-related.
Plans for a public memorial to mark that event were announced this week by Victorian Premier Andrews.

Victoria Police chief Shane Patton said investigators have found no evidence to suggest a link with terrorism and they had not established any relationship between the two men.
The incident had chilling echoes of several attacks by Islamist militants in various parts of the world over the past few years.
In January, four people were killed and more than 20 injured when a man deliberately drove into pedestrians at a spot just a few hundred metres away from Thursday's incident, though that was not terrorism-related.

Australia has been on a "high" national threat level since 2015, citing the likelihood of attacks by Australians radicalised in Iraq and Syria.
A staunch ally of the United States and its campaign against Isis in Syria and Iraq, Australia believes more than 100 of its citizens are fighting there.

Witnesses told Sky News the car ran a red light, sped up and then struck the pedestrians in an area with a 25-mile-per-hour speed limit.
"As it (the car) approached this intersection ... it just mowed everybody down, people were flying everywhere," one witness who identified herself only as Sue told radio station 3AW.
Police said in a statement they had "saturated the ... area in the vicinity of Flinders, Elizabeth and Swanston streets to ensure community safety."
