Police have charged 10 people with murder over a Brisbane brawl that left a teenager dead and several others critically injured.
Girum Mekonnen, 19, died after a fight between two groups of about 20 African youths at playing fields in Zillmere on Sunday afternoon.
Ten men aged between 18 and 32 are in police custody and will face the Brisbane Magistrate's Court on Thursday on a string of charges.
They have each been charged with one count of murder, 12 counts each of acts intended to cause grievous bodily harm and one count each of affray and disobedience to lawful order.
Detective Superintendent Tony Fleming earlier told reporters it will be alleged those involved went to Zillmere with the intent to assault the victims.
"This was an event that was highly confrontational and has been traumatic for the victims of the crime and their families," he said.
"It's just unacceptable to have people in a public space who are going about their business then attacked this way."
Paramedics took 11 people to hospital suffering stab wounds and blunt force injuries after one group attacked another with knives and baseball bats.
Some of the victims were knifed in their torso, pelvis, head and face.
Three people remain in hospital with one in a serious condition.
Police believe three carloads of people arrived at the Zillmere park seeking retribution for another incident in Brisbane's west on September 8.
Earlier, police said they were concerned some victims won't cooperate with investigators and may take matters into their own hands.
"It's a horrific, unacceptable attack in our society," Det Supt Fleming said.
"But retribution is not going to solve the problem."
Det Supt Fleming says more people may be charged.
