A CUSTOMER entered a pub, asked to speak to a barman and then punched him once in the face, a court heard.
Mark Walsh (34) left the barman with a broken nose and a fractured eye socket following the attack.
Judge David McHugh adjourned the matter to a date in March for sentencing.
The defendant, with an address at Lanesborough Mews, St Margaret's Road in Finglas, admitted before Blanchardstown District Court to seriously assaulting another man.
The assault, contrary to the non fatal offences against the person act, took place at The Deputy Mayor pub in Meakstown on July 17 last year.
In relation to the allegation, Sergeant Mary Doherty previously said that Walsh entered the bar and asked to speak to a barman, before punching him once in the face.
Sgt Doherty said the barman suffered a fractured eye socket and a broken nose in the attack, and has been on long-term sick leave ever since.
A medical report of the barman's injuries was previously handed into court.
Defence solicitor Valerie Buckley asked the judge to adjourn sentencing for six weeks to allow her to bring a number of psychiatric reports to court.
