As it happened: Four dead as city reels after car mows down pedestrians

He is always smiling, loves fashion and is adored by his friends.

But Angelo Gargasoulas had a fractured relationship with his brother Dimitrious or "Jimmy" – the 26-year-old who allegedly mowed down dozens of people in the CBD and killed at least four people

Earlier in the day in a Windsor public housing unit on Raleigh Street, Jimmy allegedly set upon his brother with a knife. The young man, who is in his 20s, was allegedly stabbed in the chest and head. He is now fighting for his life.

Angelo's friends said he had a tortured relationship with his brother, who hated the fact that he was gay.

Giuseppe, who became friends with Angelo in 2013 and did not want his surname to be published, said Jimmy refused to accept his brother's sexuality.

"Jimmy never accepted gay people, he was very homophobic person," he said.

A 32-year-old Indian woman who had been living in Australia with her husband and child was among those mowed down by the truck.

The mother, who works as an integration developer, is now in a critical condition at The Alfred with fractures to her neck and abdomen. The injuries are near her spinal cord.

She had been going on a walk through the CBD during her lunch break on Friday when she was hit by the maroon sedan driven, a relative said.
Her family live in Mumbai, and have desperately been trying to get information about her condition.

The girlfriend of the accused Bourke Street killer said she was still in shock that Dimitrious "Jimmy" Gargasoulas had allegedly run down people, killing four and injuring more than 20 others.

"I still I can't believe that it did happen because it's not supposed to happen," she said. "He didn't even have the right to.

"I'm still in shock: did that really just happen? At the moment I'm kind of lost and confused."

Serena Williams has paid tribute to the victims of yesterday's Bourke Street Mall tragedy.

The six-time Australian Open champion said she was shocked to hear about the deaths of four people on Friday after a man speeding car charged through pedestrians in the middle of Melbourne's CBD.

"It's very shocking and extremely saddening and disheartening," Williams said at her post-match press conference.

"[There are] just so many sad things are happening around the world, and even to hit so close to home where I know literally it's down the street from the tournament, close to where a lot of players are staying.

"You know, it's just an unfortunate event that you just have to really pray for everyone involved in that sad situation."

It quickly became apparent that a first aid kit was not going to cut it.

Andrew Blain raced down from his level eight office on Bourke Street with a box of emergency supplies after seeing carnage on the footpath and road. There were five people on the ground. There was blood. Lots of it.

Mr Blain crouched next to an Asian man, in his 20s, who was bleeding profusely from his head and lay at the intersection of Bourke and Queen streets. "Keep on breathing," he said.

The father-of-two handed out latex gloves to passers-by who had stopped to help the wounded. The rest of the first aid kit was useless, he said. "There were some pretty gruesome injuries, gauze and bandages weren't going to do much," he said. "We needed towels."
