The 18-year-old man, who is not named to protect the identity of his partner, is facing charges of forcible confinement, intentionally wounding, burglary, driving a car without consent and breaching a good behaviour order.

The teen, of Richardson, faced the ACT Magistrates Court on Thursday and has not pleaded to the charges.

Prosecution documents tendered to the court state that in the early hours of December 28, the defendant was driving a Holden Commodore in Latham when it came "screeching down" a street.

The defendant, who was released from custody only in September, stopped near his partner and five others.

He got out and started yelling and threatening her before he allegedly used a knife-like weapon to stab one of her friends in his left thigh.

He then allegedly grabbed his partner and dragged her into his car before driving off.

The teen is accused of committing a burglary of a Calwell premises earlier that night, which included the Commodore and about $680.

Police later that day found the pair walking in Richardson and arrested the defendant.

When police spoke with his partner, she was crying and said she was scared because "snitches get stitches".

She also said she was afraid to speak with police because people would go after her and she did not want him to get in trouble like a previous time.

A day earlier, the defendant used his mother's mobile phone to text his partner "I'm never seeing you again, I'll kill you".

"You're a dog, I want nothing to do with you anymore," he said.

In court, magistrate James Stewart denied bail, saying the defendant faced potential jail time if convicted.

Mr Stewart said the defendant's partner was "brazenly taken off the streets" and that he may commit "justice interference-type offending" if released on bail.

"The defendant for his young age has a significant history for breaching court orders and a concerning history of escape charges," Mr Stewart said.

He said the defendant's criminal history included a partially suspended 14-month jail term by the supreme court for helping a person in custody escape and joint-commission aggravated burglary.

The court also heard the defendant had ADHD and he suffered a brain injury at nine years old.

However, Mr Stewart said: "nothing in the materials indicate to me that he has a lack of capacity, physically or mentally, to offend".

The case returns to court on January 10.
