The attack
About 4.20pm, a blue utility mounted the footpath on Bourke Street, near the corner of Swanston Street, and erupted in flames. A man now identified as Hassan Khalif Shire Ali got out of the vehicle.
He attacked pedestrians, fatally stabbing Pellegrini's co-owner 74-year-old grandfather Sisto Malaspina.
It is believed he then attacked 58-year-old Rodney Patterson and a 24-year-old security guard.
Patterson suffered a head injury and is in a stable condition at The Alfred hospital, while the security guard suffered a neck injury and is in a stable condition at the Royal Melbourne Hospital.
Transit police arrived and Shire Ali punched one of them through a police car window.
The two police officers tried to stop and arrest him, as other officers flooded the scene.
Shire Ali then produced a knife and lunged at the police officers.
One bystander, now known as homeless man Michael Rogers, tried to assist police by ramming a shopping trolley between them and Shire Ali.
Another bystander used a traffic cone, while a third man picked up a cafe chair to try to fend off the attacker.
Shire Ali was then shot by police in the chest and fell to the ground.
He was taken to the Royal Melbourne Hospital under police guard in a critical condition, but died on the operating table.
Police have said it was a lone-person terror attack, and that the threat has been mitigated.
An hour after the attack, the block of Bourke Street between Russell and Swanston streets was evacuated and the city's warning system was used for the first time.
The streets remained closed until about 8am on Saturday.
The perpetrator
Police have spoken to Shire Ali's wife, parents and siblings.
His family's home in Werribee and the property where he lived in a backyard bungalow were raided by police on Saturday and combed for evidence.
Shire Ali was known have radical views and was known to counter-terrorism agencies.
"He's got family associations that are well known to us," Police Commissioner Graham Ashton said on Friday night.
His passport was seized in 2015 when he made plans to travel to Syria.
Shire Ali also had a criminal history for cannabis use, theft and driving offences, Mr Ashton said.
He was originally from Somalia, and police said he arrived in Australia in the 1980s as a child.
The city this weekend
There has been increased police presence in the CBD and at sporting events and gatherings over the weekend, including the racing at Flemington and Remembrance Sunday ceremonies.
The Victorian state election campaign has been suspended until noon on Sunday.
The police have been given the green light for the first time to use preventative detention, where they may detain terror suspects for four days without a court order.
Police are still appealing for anyone with footage to come forward.
