Aaron William Diebert has been convicted over car theft 15 times and is serving a 19-month sentence at the Alexander Maconochie Centre for theft and taking a car without consent.

Diebert, 24, is due to be released in September at the earliest.

But his eventual reintegration into the community could be complicated after he was charged with fresh offences in the ACT Magistrates Court on Thursday morning.

The recidivist thief stands accused of breaking into a Wanniassa home on June 28 last year.

Diebert is also alleged to have stolen a Honda trail bike, rider's gloves and a helmet and driving while disqualified on the same day.

His solicitor, Darryl Perkins, told magistrate Bernadette Boss he would make representations to the Office of the Director of Public Prosecutions about the charges.

Diebert has yet to enter pleas to the allegations.

The new charges date back to a month before the crimes for which Diebert is doing time at present.

In July Diebert had been on parole for just weeks when it is alleged a member of the public spotted him from her apartment window fiddling with the lock of a Subaru Impreza.

She alleges that she watched him get in the car before moving on to two other Subaru Liberty sedans, eventually driving away in one.

The witness called police, telling them the man was driving away on Vernon Circle heading towards Parliament House.

Police allege that they went to the Questacon car park and found Diebert near the stolen car.

At a sentencing hearing before chief magistrate Lorraine Walker last September the court heard Diebert was a father of one, with another on the way, and came from a loving family.

But the court also heard the family had drawn a line in the sand, refusing to support him unless he kicked his drug habit.

At the time Ms Walker said Diebert's crimes had ''plagued the community''.

Diebert is due back in court this month.
