A SEBASTOPOL man had consumed about 20 stubbies of beer and a Valium tablet when he approached a man working in his shed, then put him in a headlock, threatened to kill his family and stole his car, a court has heard.Robert Ian Kirkwood, 26, pleaded guilty to 10 charges in Ballarat Magistrates Court yesterday, just over 12 hours after the ordeal took place.Among the charges, he pleaded guilty to robbery, false imprisonment and theft of a motor vehicle.The court heard the victim was working on his car about 10pm on Wednesday night when Kirkwood grabbed him and put him in a headlock, demanding money and threatening to smash a stubby of beer on his face.When the victim said he would go inside to get money, Kirkwood said: “I’m not (expletive) stupid, you’ll go inside and call the cops”.“Don’t (expletive) with me. I know where you live and I will kill your whole family. I’m a killer, I just got out of jail.”Police prosecutor Senior Constable Steve Kent said Kirkwood claimed he had a gun in his bag, before questioning the victim about his car.The victim was eventually made to hand over the car keys.Kirkwood finally let go of him and drove off, only to crash into a mound of dirt in a paddock nearby.When police arrived at the scene the car was empty, but then Kirkwood walked up to them and asked what had happened. He matched the description given by the victim and was arrested. He then recorded a blood alcohol content of 0.137.Defence lawyer Scott Belcher said the attack was “random” and occurred after Kirkwood had consumed about 20 VB stubbies and one valium tablet.“For some unknown reason he approached the victim at his house,” Mr Belcher said. “Whilst he was uncooperative with police, he did make full admissions.”Magistrate Kay Robertson was unwilling to sentence Kirkwood yesterday, saying a pre-sentence report was necessary to determine if he had an acquired brain injury.Sentencing was adjourned until April 4.“This is a matter where a man has been held, threatened, his car stolen and his family threatened,” Ms Robertson said. “Given the evidence, I have no option but to impose imprisonment.”Follow @ballaratcourier
