Ryan McCoshan jailed for samurai sword attack on Peter Brown
A man who attacked a Chinese takeaway driver with a samurai sword has been jailed for four years.
Ryan McCoshan, 26, admitted assaulting 63-year-old Peter Brown outside his grandmother's home in Dumbarton, West Dunbartonshire, on 1 September 2013.
The High Court in Glasgow heard that the attack happened after a heated row which began with a complaint about how long it had taken to open the door.
Mr Brown was seriously injured after the sword sliced into his arm bone.
Sentencing McCoshan judge Lady Rae told him: "This was an appalling attack on a man in his sixties who was at least initially going about his business as a delivery driver.
"I accept there was a heated argument between you and the delivery driver. But after he left the house you chased after him and struck him with the weapon. You caused him a very serious injury."
Lady Rae told McCoshan that, but for his early plea of guilty, she would have jailed him for six years.
McCoshan admitted assaulting Mr Brown to his permanent disfigurement and impairment.
The court heard Mr Brown needed a blood transfusion and vital surgery following the attack.
His arm wound required 37 staples following an operation. He has been left badly scarred and has nerve damage which could be permanent.
The court heard he can no longer work and has difficulty carrying out simple tasks - such as dressing himself - due to the loss of strength in his arm.
Defence counsel Ronnie Renucci said: "The argument was started by the delivery driver, who was annoyed at how long Mr McCoshan took to answer the door.
"This offence was out of character and is unlikely to be repeated. He has shown appropriate remorse and empathy with the victim in this case."
