The teen, who was one the young people involved in the riot that left staff hospitalised, was sentenced in February this year for a number of assault charges to which he pleaded guilty.

He was in the community for only four months before he was caught by police in Conder for driving unlicensed and failing to stop, charges to which he pleaded guilty.

Court documents state he was going 130km/h in an 80km/h zone before he lost control of the car while trying to turn.

Police then found the car in Kambah with the defendant, who had only just turned 18, nearby.

On Friday, he appeared via video link in the ACT Supreme Court, which initially granted him bail before the magistrates court denied.

The courts heard that by virtue of him entering guilty pleas to the driving charges he had breached the suspended jail term.

Magistrate Glenn Theakston said the defendant had a "long and extensive history, demonstrating non-compliance with conditions proposed by the courts but also social norms".

"The real question here is the risk to the community," Mr Theakston said.

"The issue here is I cannot be confident he would do the right thing.

"The offences before the court today. There's a real risk that he could hurt someone or even kill them."

Earlier in the hearings, the defendant's lawyer, Solitaire Zahnleiter, argued for bail based on his change of circumstances, which included the prosecution withdrawing other charges from the driving incident in June.

Ms Zahnleiter proposed house arrest that included her client living with his mother and tendered a number of reference letters, including one related to schooling.

She also said he had plans to move forward an intended to attend university and work with young people.

Prosecutor Nathan Deakes opposed bail, saying the defendant had already been sentenced for 50 previous offences.

Mr Deakes said previous sentences had not deterred the defendant from reoffending.

The teen, remanded in custody at the Alexander Maconochie Centre, will front court again in November.
