Josh Powell, aged 19, of Ballinacurra, Kinsale, Co Cork, was given the suspended 12-month sentence at Cork Circuit Criminal Court for engaging with others in an act of violent disorder on September 15, 2013.
That case arose out of his peripheral role in the mugging of a young man at Model Farm Rd who was walking home from a night out.
Garda Gillian Meaney said Powell got the suspended jail term on June 23, 2014.
Two months later, Garda Meaney arrested Powell outside Rochestown Park Hotel for public order offences. He had been put out of the hotel for his behaviour on the night. Garda Meaney encountered him in the hotel car park and found that he was extremely intoxicated.
She said Powell threatened herself and her colleague that he would come after them and slit their throats.
Dermot Sheehan, defending, said the accused was apologetic to gardaí shortly afterwards and was in full-time employment. He said the accused knew he should not have been behaving in this way, in particular because of the suspended jail term hanging over him.
Judge Seán Ó Donnabháin said: “When a person gets a suspended sentence (and re-offends so soon) there has to be some element of a custodial sentence. This lad is stretching the elastic much too far.
“He did not properly take advantage of the chances given to him.”
The judge remanded him in custody until February 25.
