Shirtless man on Patrick Street warned passers-by he would 'f*** them up'

People walking on Patrick Street in Cork city were challenged by a shirtless man who warned that they didn’t know who they were dealing with and that he would "fuck them up".

Judge Mary Dorgan has jailed Jake O’Sullivan, aged 25, of 22 Fairfield Rd, Farranree, Cork, for two months for “the rather awful nature of what happened”.

At Cork District Court, Sergeant Gearóid Davis outlined the background to the incident, which occurred at 11.20pm on October 25, 2025.

Gardaí responded to reports of an altercation on Patrick Street. On arrival, they observed O'Sullivan who had his t-shirt removed. He was shouting verbal abuse at passers-by, saying, “I’ll fuck you up" and "You don’t know who I am".

“He was doing this in a threatening and abusive manner with clenched fists, shouting with such force that spittle was projecting from his mouth. He was unsteady on his feet, his speech was slurred, and there was a strong smell of intoxicating liquor coming from him. 

“He was arrested and taken to the Bridewell Garda Station.” 

O'Sullivan was later charged with engaging in threatening behaviour and being drunk and a source of danger to himself or others.

Sergeant Davis said O’Sullivan had 49 previous convictions, including one for engaging in violent disorder under the Public Order Act.

Shane Collins Daly, solicitor, said the accused was pleading guilty at the earliest opportunity.
