A WANGARATTA teen who is accused of stabbing a 37-year-old man at a Wangaratta home on Friday night was “blacked out” drunk, a court has heard.

Appearing virtually from custody at Shepparton Magistrates’ Court on Monday, the 18-year-old looked visibly distressed as the court heard of an incident which left the victim paralysed and “unlikely to walk again”.

The Wangaratta teen was facing two charges of allegedly using a knife to recklessly and intentionally cause serious injury to a 37-year-old male.

Detective Senior Constable Thomas Lonsdale of Wangaratta Family Violence Investigation Unit said the victim was stabbed once in the left arm, causing a laceration, and once in the mid torso, which left a puncture wound to the spine and partially tore a spinal cord.

“I’ve been told the injuries are life changing and it’s unlikely he’ll walk again,” he said.

The injured man was airlifted to The Alfred Hospital in Melbourne where he remained on Monday, yet to make a statement to police.

Det Sen Const Lonsdale said the defendant told police he couldn’t remember anything about the incident, having allegedly drank one litre of Jameson whiskey throughout the day.

“He spends most of his income on alcohol which he drinks daily,” he said.

In his time in custody, Det Sen Const Lonsdale said the defendant had been uncooperative with staff in Wangaratta and had been spitting on cameras.

“He is an unacceptable risk to the community if released…he is known to police to be drunk often,” he said.

The teenager's father appeared as a witness testifying to house his son if released, but police prosecutor Senior Constable Ramadan Hamidon raised concerns about the “lack of control” the father had over his son when he became agitated.

The court viewed police body camera footage of four officers responding to a noise complaint at the defendant's address earlier this month.

The accused, his brother and father were celebrating a 16th birthday when police arrived and the defendant came out visibly drunk, loudly verbally abusing officers.

The defendant's father attempted to calm the situation, telling police "he’ll lose the plot if you don’t go away”.

At court, the father said due to a difficult upbringing, his son held a prejudice against authority and gets frightened when he sees police.

He said he was “the only one” that could calm him down.

“We’ve tried to get him help for a long time… he’s a very emotional kid,” he said.

Magistrate Olivia Trumble said she was concerned by the behaviour of the defendant, particularly in the video shown to court and he would be an unacceptable risk to the community if he was released to live with his father.

Magistrate Trumble adjourned the bail application to Thursday, awaiting assessments from a psychologist and a bail support program.

"It is really important in those two assessments you talk about what your difficulties are and what you need help with," she said.

"Everything is not hunky-dory."

Th investigation into the alleged Wangaratta stabbing incident is ongoing.

Anyone with information or CCTV footage was urged to contact Wangaratta police on (03) 5723 0888 or CrimeStoppers on 1800 333 000.
