A man is in hospital recovering from surgery after being left with a collapsed lung after an allegedly "completely unexplained and random" road rage stabbing.
Nikorn Phonsaya pleaded not guilty to inflicting grievous bodily harm and intentionally wounding a person on Tuesday in the ACT Magistrates Court.
He was subject to a good behaviour order and a suspended sentence at the time of the alleged road rage attack in Franklin last weekend.
According to a police media release, the incident allegedly began between 1.45pm and 2.10pm on Sunday when a grey Subaru Liberty pulled in behind a black Mitsubishi Lancer on Flemington Road, Mitchell.
Police believe the drivers of the two vehicles then began "interacting" while driving north on Flemington Road.
This continued for some time until eventually both vehicles stopped on Nullarbor Avenue in Franklin.
Both drivers left their vehicles, and police allege that in the altercation between the pair which followed, the driver of the Mitsubishi received a stab wound to the chest.
The victim was driven to hospital and police were notified about the incident.
On Monday afternoon, police executed a search warrant on the 29-year-old man's residence in Florey.
During the search, police located a number of items which they believe were linked to the incident, including clothing, a knife and blood on the Subaru.
In opposing bail, prosecutor Ilsa Hattam said the alleged road rage incident left the victim in hospital with a collapsed lung.
She said the man had undergone surgery.
"[It was a] completely unexplained and random act of violence," the lawyer said.
Ms Hattam also said Phonsaya had a history of failing to appear in court.
Phonsaya's lawyer said there were significance issues with the prosecution's case.
He said strict bail conditions, including not leaving the family home without his sister or mother besides work, would ameliorate any risks to the community or of failing to appear.
Phonsaya was supported in court by emotional family members.
His application for bail was denied by Magistrate Robert Cook.
He said the allegations were of "significant violence acted out in a public place", and was not convinced suggested bail conditions would ameliorate risks to the public.
Phonsaya is expected to return to court next month.
