A 17-year-old boy charged with attempted murder has been remanded in custody after an alleged fight ended in a stabbing in the Brisbane suburb of Acacia Ridge.
Police allege two men were seen fighting on the footpath outside a Gregory St address at 2.30pm on Friday, before the 17-year-old brought out a knife and stabbed a 19-year-old man multiple times.
"Witnesses said they heard a fight, raised voices and believe there was a wrestle on the ground and what they believe was punches thrown," Inspector Karl Hahne told reporters on Friday.
"One of the witnesses said when the two males parted, that's when she saw a knife in one of the males' hands ... she realised that possibly somebody had been stabbed."
Insp Hahne said the victim suffered wounds to his legs and stomach and was rushed to Princess Alexandra Hospital where he remains with life-threatening injuries.
Police located the weapon on the street which Insp Hahne said was a curved hunting or fishing knife between 25cm and 30cm long.
The 17-year-old was found close to the scene and arrested without any resistance.
"Due to the fact that a person has been located with stab wounds, police obviously take a cautionary approach," Insp Hahne said.
"(Officers) tactically probed the gentleman and asked him to basically put his hands out where they could see them and he did, he complied."
The reason behind the altercation between the two men will form the police investigation.
Anyone with dashcam footage of the 19-year-old walking along Gregory St has been asked to contact investigators.
The teenager has been charged with one count each of attempted murder, threatening violence, and possession of a knife in a public space.
He was remanded in custody and is set to face court again on June 27.
