TWENTY seconds trying to rob a convenience store will mean six months behind bars for one teen.
Jake Michael Masteika, 19, pleaded guilty at the Ipswich District Court to attempted armed robbery in company.
On September 7 last year Masteika and another teenager were taking drugs, including cannabis and methylamphetamines, at a Raceview address.
They decided to hold up a nearby convenience store.
The pair armed themselves with long kitchen knives and put on hooded jumpers to hide their faces.
Around 6.15pm they entered the convenience store and Masteika's co-offender raised his knife at the 54-year-old owner of the store who was working alone.
The owner threw a battery at the pair and jumped behind the counter.
The pair then fled the store empty handed.
The court heard their attempt to rob the store lasted only 20 seconds.
Despite attempting to disguise themselves with hoodies the pair was identified on CCTV when a police officer recognising Masteika.
Police then located and spoke to Masteika who initially denied being involved in the attempted robbery until he was told of the CCTV footage.
He then told police they had been taking drugs and decided to rob the store with the intention of stealing cigarettes and money.
The court heard Masteika had a lengthy juvenile history.
The 18-year-old co-offender, who had no juvenile history but was on bail for another armed robbery at the time, has already been sentenced to two years prison, to serve six months.
Judge Sarah Bradley said there was a degree of premeditation to the attempt when the pair armed themselves with knives and tried to disguise themselves.
"This is a pretty serious example, albeit fleeting, of armed robbery," she said.
"Clearly this would have been a terrifying experience for (the store owner)."
Judge Bradley sentenced Masteika to two years prison, with a parole release date of October 5.
