The man who allegedly drove into pedestrians in Melbourne's CBD yesterday, killing four and leaving more than 30 injured, is expected to be charged by police today.

A 10-year-old girl, a 25-year-old man and 32-year-old woman were killed at the scene and a 33-year-old man died in hospital last night after a Holden Commodore allegedly driven by 26-year-old Dimitrious "Jimmy" Gargasoulas mowed down people in the Bourke Street pedestrian mall just after 1.30pm.

A further 31 people were injured in the rampage, and an infant is among five people still fighting for life.

Victoria Police Deputy Commissioner Andrew Crisp said police hoped to interview and charge Mr Gargasoulas as soon as today.

"We're certainly hoping we can interview the male today," Deputy Commissioner Crisp told Weekend Today this morning.

"He did receive a gunshot wound to the arm, it's certainly not life threatening and we're hoping we can interview and charge later today."

Deputy Commissioner Crisp said the incident had been traumatic for emergency services.

"Words really can't explain how horrific this particular situation has been for victims, for families, for police and other emergency services and the broader community," he said.

It’s also alleged Mr Gargasoulas stabbed his brother in the hours before the CBD incident.

Detectives believe the Bourke Street attack is linked to the stabbing of Mr Gargasoulas' brother Angelo, who is fighting for life in hospital.

Mr Gargasoulas allegedly stabbed his brother repeatedly during an argument at a property in Raleigh Street in Windsor.

Mr Gargasoulas fled but later appeared in the background of 9NEWS reporter Neary Ty's live cross from the scene, waving and swearing at the camera.

Following the stabbing, it is alleged Mr Gargasoulas took a woman, who is known to him, hostage in his car.

She managed to escape on the Bolte Bridge before the car was driven into the Melbourne CBD.

Mr Gargasoulas was seen doing burn-outs near Flinders Street Station before he turned onto Swanston Street at around 1.45pm and turned left into the busy Bourke Street pedestrian mall.

Police shot Mr Gargasoulas, who was the only person in the car at the time.

He was arrested near the corner of Bourke and William Streets, and was seen handcuffed on the ground, shirtless and wearing a pair of red underwear.

Premier Daniel Andrews has labelled the attack an "evil criminal act" and pledged the governments support for those affected.

"A terrible criminal act was committed in the CBD of our great city," Mr Andrews said this afternoon.

"Our hearts are breaking.

"This is a heart-breaking incident and one that has torn families apart."

Witnesses reported hearing at least five gunshots before the man was arrested.

"There's someone on the middle of the ground and there's blood all over the street," Rishi Hathiramani, a CBD shopkeeper, said.

A number of CBD businesses were placed into lockdown, while others were evacuated.

"A heap of people ran into my store, it was horrible. Half of my staff are in tears," a Strandbags manager said.

City office worker William Mulholland said he came out of a laneway and saw a number of people lying on the pavement receiving CPR from police and emergency workers.

[SYDNEY] A man deliberately drove into pedestrians, killing three and injuring at least 20 in the centre of Australia’s second largest city Melbourne on Friday, but police said the lunch-time incident was not terror-related.

Video footage from a witness showed a maroon coloured car driving around in circles in an intersection outside Flinders St railway station in the city’s central business district, with the driver hanging his arm out the window.

Two people approached the car, apparently trying to stop it.

“He was half hanging outside the car...he was just so reckless...he just didn’t care,” witness Laura Pollson told the Australian Broadcasting Corp.

The man then drove up a pedestrian mall, deliberately ploughing into people, Victoria state police said. A shop video showed several people diving into a convenience store as the car sped along the footpath.

“A male deliberately drove into pedestrians in the Bourke Street mall, and we currently have three deceased and at least 20 injuries,” Victoria Police acting commander Stuart Bateson told reporters.

“We have the offender in custody. There is no further threat to the public at this stage. I can also confirm that this is not a CT (counter-terrorism) related incident.” The incident was believed to be related to an overnight stabbing in the city, Commander Bateson added.

Photographs published by local media showed a stationary, badly damaged car with a nearby man in red underwear pinned to the ground by police.

Witness Maria Kitjapanon told Melbourne’s The Age newspaper that the car was rammed by a police car and that police fired shots into the car before pulling the driver out.

“There were probably 10 police surrounding that guy’s car, with guns drawn, and they fired into the car. Then they dragged someone out via the passengers side, then all 10 of them sat on top of him,” she said.

Police have locked down the city and suspended tram services.

Melbourne is currently hosting the Australian Open tennis grand slam and is packed with thousands of extra tourists, only a few blocks from where the incident occurred. Police said the tennis tournament continued to operate as normal.

People who were in the Melbourne CBD and witnessed the event as it unfolded are asked to contact Crime Stoppers on 1800 333 000.</s>At least four people were killed and 20 more injured when a man deliberately drove his car into a crowd of pedestrians at a mall in Melbourne, Australia, according to officials. In a statement released Friday, Victoria state police said a young child was among the dead.

"The incident is not terrorism related," the department added.

The man was seen driving erratically in circles outside the mall, leaning out his widow and shouting at passersby, before police say he accelerated into the pedestrians in the middle of the afternoon.

"We witnessed about half a dozen people that ricocheted off the car one way or another," one witness tells Reuters. "I saw one person fly up almost roof level of the car as they got thrown up against one of the retail stores."

Officers shot the driver and placed him in custody, "where he is being treated for non-life threatening injuries," police say.

Mike O'Brien, the head surgeon at Royal Children's Hospital, tells The New York Times that four children have been hospitalized, including a 3-month-old in critical condition.

At a news conference, Victoria Police Commissioner Graham Ashton said the 26-year-old suspect had "an extensive family violence history. He has come to our attention on many occasions in the past. We have mental health and drug-related issues in the background of this particular person," according to the Australian Broadcasting Corporation.

Authorities have not yet released his name.

Police say they had been pursuing the suspect in connection with a stabbing early Friday. According to authorities, the man also allegedly abducted a woman he knows and held her hostage in his car — though she managed to escape before it plowed into the crowd.

The incident comes at a particularly busy time for the city. It is hosting tourists from around the world for the Australian Open tennis tournament, which got underway earlier this month.</s>Three persons were killed and 20 injured when a car hit pedestrians in the centre of Australia's second-largest city Melbourne on Friday, police and emergency services said.

Australian media reported that the car was driving erratically before the incident, which occurred during the city's busy lunchtime, and at least one shot was fired.

Police have locked down the city and suspended tram services after the incident in the heart of the popular Bourke Street shopping mall area.

Australia, a staunch U.S. ally, has been on heightened alert for attacks by home-grown radicals since 2014 and authorities have said they have thwarted a number of plots. There have been several "lone wolf" assaults, including a 2014 cafe siege in Sydney that left two hostages and the gunman dead.

"At this stage it is believed a man driving a vehicle has struck a number of pedestrians in Bourke and Queen St just before 2 pm," Victoria state police said in a statement posted on their official twitter account.

Police confirmed that one person was dead and that a man had been arrested. Emergency services are treating the incident as a "mass casualty event" and hospitals have been put on "Code Red" to accept casualties.
