Jason Allen Tattersall had just been released from prison in February when he learnt his ex-girlfriend had slept with 18-year-old Steven Jiminez, the Daily Telegraph reports. The 35-year-old father-of-two called the teenager and threatened him before going to his home in Albion Park near Wollongong. When Tattersall arrived, he punched and kicked Jiminez on the kitchen floor before hitting him with a baseball bat.

He then said: "Have you learnt your lesson c ... ? I'm gonna overdose you on heroin and leave you to die. That's what a dirty c ... gets."Tattersall then used a tattoo gun to put the word "dog" on Mr Jiminez's forehead. Mr Jiminez said in a victim impact statement that he couldn't afford to have the tattoo removed and that he and his mother were constantly "on edge". "The tattoo has left me unemployable ... I cannot get a job ... the shock on people's faces just doesn't describe it," he said.

Judge Paul Conlon said yesterday Tattersall's "criminal behaviour was towards the high end of the range, but just short of the worst-case category."He pleaded guilty to aggravated kidnapped and was sentenced to a maximum 14 years in jail.
