A Canberra man who robbed a Conder bottle shop at knife point will spend the next two years behind bars.

Benjamin Allwell, 27, was on Wednesday convicted in the ACT Supreme Court of aggravated robbery after pleading guilty to holding up Corks Liquor last year.

On September 17, Allwell, who was wearing a balaclava and socks on his hands, entered the store about 7.17pm and threatened the sole staff member with a knife.

The woman filled up a bag with cash, cigarettes and bottles of liquor and he left the shop.

The employee locked the store’s doors and called police, who came across Allwell soon after.

But the offender was not arrested and charged until June this year.

Acting Justice John Nield was also asked to resentence Allwell on charges from 2010 and 2011.

The court heard Allwell had attacked a car, dinting panels and smashing windows, in August 2010.

In November the following year, he assaulted his partner, punched holes in a gyprock wall and broke a cot.

The court heard Allwell failed to complete a period of weekend detention for the charges and subsequently served a term of full-time imprisonment until May this year.

He has been in custody since his June arrest.

Justice Nield jailed Allwell for four months for damaging the car, nine months for the assault, and four years for the knifepoint robbery.

The judge ordered the terms be served both concurrently and consequently, with a total sentence of three-and-a-half years.

The sentence was backdated to take into account time spent in custody.

Allwell will be eligible for parole in September 2015.

Justice Nield also ordered he pay $500 compensation to Corks Liquor.
