Mathew Morrison, 20, of Heriot, pleaded guilty at Selkirk Sheriff Court to butting his victim at the Indigo Rooms in the town’s Overhaugh Street.
Morrison also admitted behaving in a threatening or abusive manner.
Depute fiscal Fiona Hamilton told Selkirk Sheriff Court the accused approached Alan Smith and, in an unprovoked attack, butted him, breaking his nose and also causing a cut.
She explained that Mr Smith’s brother had got involved in an altercation and Morrison told him: “Who the f*** are you? If you don’t back off, I will do the same to you.”
Outside the nightclub, the accused threatened to kill Mr Smith’s brother and there were exchanges between the pair over a ripped jumper.
Defence lawyer Graham Clark: “I think something was said to start it off. It is all to do with drink.
“He was employed as a civil servant, but took the decision to resign over this and is now working in a warehouse.
“It was out of character and he has shown genuine remorse.”
Sheriff Raymond McMenamin imposed a community payback order involving 150 hours’ unpaid work and a year’s supervision, as well as a compensation order of £1,000 for his victim.
