On Sunday (20/2) at around 12.50am, the victim, a man aged in his forties, was involved in a confrontation with three men on the forecourt of the Jet petrol station on Micklefield Road.
The victim started to walk home with his partner when two vehicles, one believed to be a silver Audi, pulled up behind him.
One of the offenders thrust a machete towards the victim, causing a large cut on his lower arm, before returning to their vehicles and driving off.
