Postcode Wars in Sydney's west are being investigated as a possible cause of the death of a teenage boy in an apparent vicious brawl.
The teen was allegedly stabbed to death on the streets of Blacktown about 10 p.m. on Wednesday.
They were transferred to the Westmead Children's Hospital by ambulance. On Friday morning, one person was in critical condition.
About a dozen people are believed to have been engaged in the alleged deadly brawl, according to police.
Several people were arrested in the hours that followed after a PolAir chopper conducted a thorough search.
For a series of offenses, one adult, Panashe Karise (21), as well as four teens (age 17) have been charged. However, he was not charged.
As soon as the news broke, friends filled social media with condolences for the 18-year-old artist.
As one person put it, Ollie should "soar high" and another described him as a "solja".
Not far from the Doonside housing commission, a 16 year old named Jason Galleghan was found dead just four weeks before.
Steve Eggington, Superintendent of the Blacktown Police, said that police were also looking into 'postcode battles' in this alleged event.
Lieutenant Eggington noted that the alleged violence was "very confronting" and that it was currently part of the inquiry.
Tragically, young children are becoming embroiled in these kinds of occurrences.
Officers led a young man away from the scene with his hands in paper bags to preserve evidence, according to a shocking video.
Officers allegedly found broken butcher's knives and batons during a line search on Thursday.
The crime scene spanned roughly a kilometer, according to authorities.
The police believe two groups were involved in the incident, and they're asking for any CCTV footage or in-car video from witnesses who may have captured it.
An assault charge, not disclosing who was driving and who was riding with, driving while suspended, and violating public health orders were all filed against Karise.
There were rigorous terms attached to his release, including that he not go within 1km of William St. in Blacktown and that he not approach any prosecution witnesses.
No Karise should leave his house between the hours of 8 p.m and 6 a.m
Affray and failure to comply with public health requirements were filed against each of the 17-year-olds.
Bail for all four of them has been denied by police. Parramatta Children's Court will hear the cases of two of them today, while the rest will be heard in the coming weeks.
His friends swear that his needless death will not be forgotten.
Jason Galleghan, 16, has nice eyes and round cheeks. He was allegedly battered to death by a group of teens in Sydney's west four weeks ago.
Jason was allegedly beaten to death in a Doonside housing commission residence by four lads and two females aged 13 to 19.
A friend of Jason's has launched a campaign to end senseless juvenile violence, and Jason's mother has given permission for his identify to be disclosed.
In the words of Ouwais Menzel, Jason was a person who cared about others, was kind and compassionate, and never hurt anyone.
It was a tradition for them to go to the beach and bodysurf together when they were growing up in South Coogee. Lifeguard was even on his bucket list for Jason.
However, Mr Menzel said, 'his hopes and dreams have been taken from him'
Young People Against Violence is a new initiative led by Mr. Menzel and volunteers to say 'enough is enough'.
It has pledged support for a memorial painting for Jason to be built in Blacktown next month.
Memorials are being planned for Coogee and Doonside in the future. They also plan to construct youth centers in the future to divert children away from violence in the country.
It was Mr Menzel who said: 'All I'm doing now is because I lost a good buddy.'
'It's time for all of this to cease being brushed under the rug and disregarded.'
This time, we're going to make a difference on a national scale.
Jason's friends made a wonderful attempt, and it will be a part of his legacy.
He was declared brain dead by physicians at Westmead Hospital, and Jason's mother consented to donate his organs to those in need.
His aunt wrote on a community fundraising page that his gut-wrenching decision had saved five more lives.
Many of Jason's friends and family members came out to show their support about a fortnight ago.
There were dozens of balloons, floral bouquets, and notes of support pinned to the fence.
One of the placards called for an end to the violence, while another demanded justice for the youngster who had been murdered.
"You Never Said Goodbye" was another heartbreaking poem. You would not have perished if only love had been able to save you.
You were loved by your mother in life, and she loves you much more in death. You possess a special place in her heart that no one else could ever fill. However, you weren't the only one who left. The day you got your wings, a part of her went with.'
Police allege horrific sights took place inside the residence, and it was an effective and poignant counterpoint to those awful scenes.
A argument over AirPods and 'postcode wars' between adolescents from various parts of western Sydney allegedly led to Jason being enticed there.
As a result of the claimed beating that occurred on the afternoon of August 4, Jason was left brain dead, with collapsed lungs, as well as facial and torso injuries.
A 19-year-old woman will be charged for calling an ambulance after five other suspected criminals had fled.
Previously, another of the teens accused of Jason's death has been charged with punching him 52 times.
Police will use a video of the alleged brutal assault as evidence against the youths.
According to government officials, the property where the alleged crime occurred is likely to be home to another family in the future.
As long as Dawson's case is pending in court, that day won't come anytime soon.
Authorities are expected to report the property's history if or when it becomes accessible.
Jason's mother has asked for privacy while she grieves over her son's death. Locals raised $50,000 to help the family.
