A man attacked a former friend over a historic dispute over a £20 debt, leaving him with a fracture to his face, a court has heard.
Ian Gray, of Harcourt Road, Lancaster, was jailed for 45 weeks by a judge following a hearing at Preston Crown Court.
He pleaded guilty, on what should have been the day of his trial, to a single count of causing actual bodily harm.
Prosecuting, Sarah Johnston told the court his victim, Lancaster man Lee Orriss, had been walking down Granville Street in Lancaster at around 5.15pm on April 29 this year.
She described how he was approached by the defendant.
Gray argued with his victim over a £20 debt he alleged he owed to him from “a long time ago”.
The 35-year-old then followed Mr Orriss, who denies owing him the money.
When the men got onto nearby Harcourt Road, Gray launched an attack on him, delivering a single punch to his face.
The blow to his head caused the victim to fall to the ground.
It is understood he was knocked unconscious in the incident.
He was later treated in hospital in Lancaster for his injuries.
Judge Christopher Cornwall was told the victim suffered a fracture to his cheekbone.
He also suffered severe bruising.
The judge ruled a custodial sentence was necessary.
