AN RAF serviceman who used a knife to attack a man he found in his ex-girlfriend's Llanelli flat has been jailed for 16 months.
Jeffrey Roberts has lost his promising role in the RAF after the attack, which left his victim with a series of wounds.
Jamie Maunder met Kristina Evans in Swansea's Wind Street on February 2, 2012, and they had taken a taxi back to her flat, Swansea Crown Court heard.
The pair were watching TV when Miss Evans said her former boyfriend arrived in a jealous rage.
Prosecuting barrister Dyfed Thomas said Miss Evans said his eyes were bulging and he shouted: "I'll ****ing stab you."
Mr Maunder immediately left, but said he was worried for Miss Evans and waited in a corridor outside.
Roberts then selected a bread knife, and followed Mr Maunder outside.
Roberts, aged 31, now of Templars Place, Yeovil, came out of the flat and launched at Mr Maunder in a stabbing motion with the knife.
Mr Maunder managed to grab hold of his attacker but Roberts directed the knife towards Mr Maunder's side and back, making contact with his body.
Mr Maunder was left with a 2cm cut to his chest, two wounds, one 5cm long and the other 7cm long to his chest and another to his stomach. He also had a 5cm abrasion on his chest.
Mr Maunder, who punched Roberts several times, ran off towards the town centre, flagging down a passing car for help.
He needed 12 stitches and said he had been badly affected.
In a statement to the court, he said has remained off work since the attack and, although the wounds have healed, he is still worried about going out.
He said he had feared for his life during the attack. Mark Spackman, representing Roberts, said his client accepted it was lucky the injuries were not worse, but said he had consciously selected the bread knife because he thought any injuries would be lessened by the type of blade.
"The defendant plainly regrets having acted in the way he did," he added.
He said a number of references had expressed that Roberts would have had a long and successful career in the RAF but any hopes he had of his contract being renewed had been dashed after he pleaded guilty to causing grievous bodily harm.
He said the court faced a stark choice about whether to impose an immediate term or whether they could suspend it.
Judge Paul Thomas said it was a terrible shame he was in the dock.
He said he had acted out of jealously but that his reaction was extreme. The judge said he could not suspend the sentence.
"I have an overriding public duty to mark any knife attack with an immediate sentence," he added.
