A man who brutally beat a woman at service station is behind bars in the same prison as the man who stabbed him seven years earlier - convicted murderer Scott Alexander McDougall.
Duncan John Knight sucked in deep gasps of air as Justice John Burns delivered the sentence in the ACT Supreme Court yesterday.
The 35-year-old will spend the next three months behind bars and another seven months in periodic detention, with five months suspended.
He'll do the first stretch alongside former friend McDougall who, years before committing two brutal murders in the city's inner north, was jailed for a vicious knife assault on Knight.
In November Knight's victim was about to fill up her car at the BP service station on Canberra Avenue in Kingston when Knight came running towards her with a spanner. He smashed the car's rear window with the spanner and punched the victim in the back of the head, causing her to fall to the ground.
He kicked her repeatedly in the head and face, telling her, ''I can't believe you thought you were going to get away with it.''
She ran for the safety of the service station and another customer put themselves between the two, before Knight fled.
Police found him in the Eastlakes car park a short time later.
He was sentenced in the ACT Supreme Court yesterday on charges of assault occasioning actual bodily harm and using a carriage service to menace, harass or cause offence.
Knight sent 67 threatening messages to the victim before the assault.
The court heard the defendant, who was on amphetamines at the time of the assault, suffered from post-traumatic stress disorder, anxiety and depression.
But Justice Burns said his conduct was a ''very nasty attack'' from behind on a smaller woman.
In 2005 Knight was left with stab wounds to the neck, head and arm after an argument broke out between he and McDougall at the home Knight shared with his partner and infant child.
