A teenager accused of being in a group that carried out a "targeted attack" on a 17-year-old who remains on life support should be refused bail, a Brisbane court has been told.
Lasender Sheriff is one of 10 people aged between 15 and 19 charged with attempted murder over the alleged attack on a sleeping teenager in an apartment in the Brisbane suburb of Milton on August 28.
The victim suffered serious injuries and is still on life support in an intensive care ward nearly two weeks later, acting magistrate Rowan Silva was told on Tuesday.
Prosecutor Lauren Archer said there was no way of knowing whether the victim's condition would improve or deteriorate.
"He's quite agitated, she added.
He's not obeying commands. There's no meaningful neurological recovery at this stage."
Police say it was a "targeted attack on the victim", Ms Archer said in opposing bail for Sheriff, who turned 18 six days before the incident.
"They have received a video clip of the assault on the victim during which he is kicked in the head twice while already unconscious and bleeding," she added.
"There is audio from the lifts depicting the group celebrating."
Ms Archer said groups like the one Sheriff was involved with were "putting the lives of people at risk".
"This pack mentality cannot be condoned by the courts," she added.
Sheriff liaised with "dangerous groups of people" and there was an unacceptable risk he would reoffend, endanger the safety of the community, interfere with witnesses or possibly fail to appear in court, Ms Archer said.
He is also facing a separate charge of wilful damage for allegedly smashing a windscreen by jumping on a car in Brisbane's Fortitude Valley on August 23, the day after his 18th birthday.
But defence lawyer Ashkan Tai said concerns raised about gang activity were only "an opinion of a police officer".
"If (the prosecution are) going to allege a circumstance of aggravation with gang affiliation they should charge him accordingly," he added.
"They have the power to charge with serious organised crime ... and they haven't."
Sheriff's instructions to Mr Tai were that "something had kicked off" in the apartment after the group was invited and let in by girls.
There may be evidence of grievous bodily harm, but the prosecution "just don't have the evidence for attempted murder", Mr Tai told Mr Silva.
He argued Sheriff could be released under strict bail conditions like having a curfew, being banned from being in some Brisbane suburbs and wearing a tracker.
Mr Tai said after spending time in custody Sheriff had realised he's "playing A-grade" and knew where he would end up if he breached bail in the slightest.
He told the court Sheriff - whose mother moved from Liberia in 2003 - was young and completing his final year of school.
Mr Silva adjourned the bail application until Wednesday.
Sheriff and Dut Acot, 19, were the only two adults charged over the alleged attack.
The remainder were to face the Children's Court, with media denied access.
Acot's case is listed for committal mention in Brisbane Magistrates Court on September 27.
