A homeless teenager who attempted an armed hold-up of a Launceston pizzeria will be sentenced on Monday.
David James Oakley, 19, formerly of George Town, pleaded guilty to two counts of aggravated attempted armed robbery, setting fire to a car and injuring property.
In June last year, Oakley walked in to Pizzacom on Charles Street in the early morning with an unloaded rifle and an accomplice armed with a baton.
Oakley, who has a long history of drug addiction and suffered a possible heart-attack after going in to custody, demanded money from the shop's owner.
When the owner dived behind the counter Oakley and the accomplice began smashing the Bain Marie.
The accomplice then tried to rob a customer.
Unsuccessful, the duo fled to their stolen getaway car, joining two others, drove to Blackstone Heights and torched the vehicle.
Oakley handed himself in to police a month later and has been in custody since.
Defence Counsel Fran McCracken said her client had not hatched the plan and was deeply remorseful.
Supreme Court Chief Justice Ewan Crawford will sentence Oakley on Monday in Launceston.
