A man who put his fist through a car's rear window "pretended" to be unconscious in a garda station cell but "woke up very quickly in the ambulance", a court heard.
Marian Zastinceanu (35) was also aggressive to ambulance staff, but apologised for his behaviour when he was leaving a garda station.
Judge Dermot Dempsey ordered a probation report to see if Zastinceanu is suitable to complete 240 hours of community service in lieu of two months in prison.
The defendant, of Allendale Close, Clonsilla, admitted before Swords District Court to two counts of threatening and abusive behaviour.
Gda Darren Tuffy said he was called to Ashfield Drive in Balbriggan following reports of two men fighting. He said Zastinceanu was very intoxicated, aggressive and violent.
Zastinceanu was taken to Balbriggan Garda Station but became unresponsive in the cell. He was taken away by ambulance and again became aggressive, said Gda Tuffy.
The court heard the defendant's friend had lost his car keys and Zastinceanu thought he was helping by putting his fist through the back window.
Gda Tuffy said Zastinceanu had an injury to his arm, and he received first aid at the garda station.
The officer claimed Zastin- ceanu "pretended" for a long time to be unconscious in the station cell but "woke up very quickly in the ambulance".
The court heard the defendant had never been in trouble before.
Defence solicitor Fiona D'Arcy said he was drunk and "things got out of control" but he does not have an alcohol problem.
