A GOOD Samaritan was repeatedly stabbed for trying to help a woman as she was being attacked, an Ipswich court heard.
The man had come to the aid of the woman after an altercation broke out between her and her partner at Sadliers Crossing on June 23 last year.
Christopher Mark Shersby, 19, who knew the boyfriend, grabbed the victim by the throat and held him in a headlock before he produced a knife and stabbed the man three times.
At sentencing in Ipswich District Court yesterday, the court heard the man was rushed to hospital where he underwent surgery for life-threatening injuries.
He received extensive ongoing treatment for further complications and suffers ongoing spine and kidney problems.
Shersby pleaded guilty to one count of grievous bodily harm and two counts of unlawful wounding.
He was sentenced to six years prison and will be eligible to apply for parole on February 4, 2015, after serving two years.
Judge Sarah Bradley noted the victim "still had a long way to go" on his journey to recovery.
"(He) was a complete stranger who intervened between your friend and his girlfriend (who had) been pushed to the ground," Judge Bradley said.
"You had him in a headlock and, without warning, stabbed him three times. There were very serious consequences - he took four-and-a-half months off work and still suffers significant pain and discomfort to his kidney and spine.
"You are in a position - standing there - where you could have caused the death of someone.
"And you're not a stranger to the use of knives - you have a previous conviction for going armed in a public place with a knife in October 2011."
Defence barrister Geoff Seaholme said on the night Shersby was heavily affected by drugs and alcohol, which had flared up his aggressive mood from an earlier incident.
Shersby escaped being declared a serious violent offender, which means he is not required to serve 80% of his sentence.
