Police have reopened the Bourke St Mall after yesterday's horrific rampage.
Four people have died and another 30 have been injured after a man on bail drove into crowds in Melbourne yesterday afternoon.
The man has been identified by media outlets as 26-year-old Dimitrious Gargasoulas, who is in hospital with a non-life-threatening gunshot wound to his arm.
He was well known to police with a criminal history of family violence and he had been charged on January 14 but released on bail - despite police opposition.
Police Commissioner Graham Ashton has warned the death toll could rise with five people still on the critical list. Mr Ashton said on Saturday that police hoped to interview and charge the 26-year-old sometime this weekend
"Obviously, the hospitals are still working on those critically injured people, but we do have fears - grave fears - for the health of at least two or three of those that are in that critical condition," Mr Ashton told reporters.
"It may be that that death - numbers of people killed - may still increase beyond four."
The dead include a 10-year-old girl, a man, 25, and a woman, 32, who died in Bourke St, and a 33-year-old man who died in hospital on Friday night.
The youngest among the injured is a three-month-old baby who is fighting for life in The Royal Children's Hospital, where a two-year-old is in a serious condition and a nine-year-old is in a stable condition.
Victorian Premier Daniel Andrews laid flowers on Bourke St along side many members of the public as part of a memorial paying tribute to the victims.
Mr Ashton said the areas had been reopened and there was nothing from a security perspective to make going to the city, for the Australian Open or other reasons, problematic
Yarra Trams has restored all tram services, and are currently working to restore the full timetable.
