Samurai sword attacker detained for Caithness stabbing
A teenager who stabbed a young father with a samurai sword has been locked up for four and a half years.
Anthony Robertson chased Danny Ryder with the weapon then plunged the blade into his thigh, with the point of the sword exiting at the victim's groin.
Robertson, 18, from Wick, pleaded guilty to assault at the High Court in Edinburgh.
Judge Lord Woolman also ordered him to be supervised for a further two years after his release from custody.
The attack happened during a visit by Mr Ryder to Wick from his home in Orkney on 10 October last year.
The court heard that Mr Ryder, 19, had previously had a relationship with Robertson's then girlfriend and was visiting her son.
A fight broke out between the men when Mr Ryder went to Robertson's home to collect the child.
But as he left the house, Robertson appeared with the sword, which had a blade measuring 18 inches (45cm).
The court was told that Mr Ryder tried to run off but Robertson pursued him, getting close enough to stab him.
Advocate depute Hugh Irwin said that Danny Ryder had been unable to work following the attack and had felt reluctant to travel to Wick to see his son.
Robertson admitted carrying out the assault to severe injury, permanent disfigurement and to the danger of life.
During sentencing, Lord Woolman said: "You chose to use a lethal weapon on another human being. It is fortunate you do not stand in the dock on a more serious charge."
He also pointed out that Robertson had been assessed as posing a significant risk to the public.
