A REVELLER told a garda that he would "spark him out" and that he was a "windy f***ing rat", a court heard.
Sean Donnellan (23) also drunkenly refused to go home, even though he was repeatedly told to do so by gardai.
Judge David McHugh ordered Donnellan to donate €400 to the Garda Benevolent Fund and said he'd strike out the charges.
Donnellan, of Woodford View, in Clondalkin, admitted before Blanchardstown District Court to public drunkenness and threatening and abusive behaviour.
The incident took place at Monksfield Heights in Clondalkin around 1.30am on March 9 last.
Garda David Gilmore said he was on mobile patrol when Donnellan approached him. He was drunk and unsteady on his feet and immediately abusive.
Garda Gilmore said Donnellan called him a "windy f***ing rat" and told him he would "spark him out".
The court heard Donnellan was told to go home by gardai but he refused to do so.
Defence lawyer Jennifer Jackson said Donnellan, a business and management student, had been at a 21st birthday party and was heading home.
Ms Jackson said Donnellan, who has never been in trouble before, had no excuse for his behaviour and he regretted his actions.
She asked the judge to leave him without a conviction, saying he has a long-term partner and he hopes to travel to Australia to work.
Judge McHugh ordered Donnellan to donate €400 to the Garda Benevolent Fund and said he would strike out the charges.
