"So this, on Saturday night, has completely destroyed the boy. No-one will ever know what they've done to him mentally.
"He won't leave his room. He hasn't left his room since Sunday. He won't speak. He won't do anything.
"It's happened to him twice and he's broken".
Jayden was attacked by eight men, described as being in their 20s, while walking to a nightclub to see friends.
He saw the group following him and, when he began walking faster, they ran towards him.
His father says he was punched and kicked, had a shard of glass dug into his forehead and was choked. His injuries include a fractured eye socket and significant bruising, but there are mental scars too.
Frank sat on the steps of Melbourne's Parliament House dejected this morning. From 8am he waited for the chance to speak directly to Premier Daniel Andrews about an issue he believes the Victorian leader is ignoring.
"This guy doesn't care," he said, pointing towards Parliament House.
"When I speak, I speak on behalf of my family and all Victorians. This is not about me. This is about all of us. Your son, daughter, anybody.
"Every day of the week, Dan Andrews will tell you the crime rate is down. But the severity of the crime is through the roof and he won't deal with it. Doesn't want to know about it."
He said he was "disgusted" by the way Andrews had put the issue of youth crime on the shelf.
"I'm disgusted. He has shown me no respect. He has shown Victorians no respect."
Andrews last year committed to tackling youth crime in Victoria and to work closely with the African community in relation to incidents of violence committed by African youths.
But he lashed out at Home Affairs Minister Peter Dutton when the federal MP suggested Melburnians were too scared to go to restaurants at night.
Victoria's Shadow Minister for Police, David Southwick, said the problem is real and it is time Andrews dealt with it properly.
"I think, firstly, what's happened to Jayden is horrific. It's something that should never happen on our streets, but unfortunately it is.
"We do have a gang problem in Victoria and there is not enough being done by Andrews' Labor Government to address this."
Southwick said he wants to see more police patrols to prevent attacks like the one on Saturday night from happening again.
News.com.au has approached Andrews for comment.
Police say they are following leads but have not made any arrests at this stage.
"Police are currently investigating an incident where a 19-year-old male was approached by approximately eight young people wearing dark clothing," Senior Sergeant Samantha Ryan told reporters yesterday.
"He was chased by them for a short time, and was subsequently assaulted by them."
She said it was a "cowardly attack" and one that was "spontaneous" and "opportunistic".
The attack has left Jayden and his family asking why they were targeted not once but twice.
"Jayden just says, 'Why me?' … 'Why me twice?'," Frank said.
"He doesn't understand. He's 19 years old, he's autistic. They've destroyed him once, they've destroyed him twice."
