A Dublin man has been found guilty of a public order offence, after Independent Kerry TD Michael Healy-Rae claimed the man threatened to shoot him in the head.

However, Cianán Doyle, with an address at Beechfield Road in Perrystown, Dublin 12, has avoided a conviction or sentencing in relation to the matter.

The 35-year-old denied the charge of a breach of the peace, following an incident at the junction of Dolphin's Barn and the South Circular Road on the morning of the 4 December 2018.

Michael Healy-Rae gave evidence before the Dublin District Court this morning and described being subject to an "awful tirade of abuse" while he was stopped in traffic.

He said he had travelled from Kerry to Dublin that morning, and was sitting in a line of traffic when someone in the car to his right gestured to him to roll down the window.

Mr Healy-Rae said that the man in the passenger seat became angry and cross and used abusive, bad language.

He said the man told him: "You would want a bullet put in your head" and "I would do it", and he described how he was "rattled" by this.

Mr Healy-Rae said he took out his dictaphone and recorded the registration number of the vehicle involved.

This afternoon, the accused man Cianán Doyle also gave evidence.

When asked if the exchange about a bullet happened, Mr Doyle replied "absolutely not", and later he told the prosecuting counsel "I did not say those words".

He said he was on his way to work that morning and was a front seat passenger in the car that his father was driving. His sister was also a passenger in the car.

Mr Doyle told the court that his father asked him to roll down the window and that his father engaged with Mr Healy-Rae, who was in a car to the left of them.

He said his father told Mr Healy-Rae that he was a "greedy little man", and told him that he "didn't care about the people of Kerry or Ireland", and that he only cared about himself.

Mr Doyle said that Mr Healy-Rae responded by saying "Do you think so?", and that he then became involved.

Cianán Doyle said he described the Kerry politician as a "mé féiner", said he was a "greedy f***ing man" and asked him what he was doing about the homeless situation.

Mr Doyle agreed that he had used bad language, and that he shouldn't have done that.

He said there was no aggression or threats and that he didn't think anything would come from the incident.

He described what had happened as a "politically oriented exchange" that lasted for around 30 seconds.

Cianán Doyle apologised for cursing at Mr Healy Rae and he agreed that he had a job to do.

Mr Doyle's father, Alan Doyle also gave evidence. He said his son did not make threats towards Michael Healy Rae.

In relation to the alleged threat to shoot Mr Healy-Rae, Mr Doyle's sister Sorcha Doyle said those words "were never spoken".

Judge Michael Walsh said he listened carefully to all of the evidence.

He said the "huge conflict" in this case was the allegation that the accused would put a bullet in Michael Healy Rae's head.

Judge Walsh said he found Michael Healy-Rae's evidence to be "persuasive" and that an incident did occur.

He said that it started off as "somewhat minor" but he said "I think it escalated" to something more serious.

Judge Walsh said the accused behaved in a rude and offensive manner and was satisfied that he insulted Mr Healy Rae, and described the behaviour as unacceptable.

Judge Walsh also remarked that people have to abide by proper etiquette on the roads and that failure to do so can lead to road traffic incidents.

The court heard that Mr Doyle has one previous conviction. His lawyer told the court that he is very hard working and comes from a very good family.

Judge Walsh said he was going to treat this as a "once off".

The charge was struck out leaving Mr Doyle without a conviction and the 35-year-old was ordered to a make contribution of €1,500 to the PARC road safety group.
