A man has gone on trial accused of murdering a 20-year-old man in Naas, Co Kildare in May 2014.
The prosecution claims Zoltan Almasi hit Joseph Dunne in the head with a baseball bat outside his house at Harbour View in Naas.
The jury of six men and six women was told it will be alleged that he attacked him after Mr Dunne hit his van.
Zoltan Almasi was born in Serbia, but became a Hungarian national in 2007 and moved to Ireland sometime later.
In 2014, Mr Almasi (44) was working as a courier. His van was parked outside his home on May 16th 2014, the evening the murder was alleged to have occurred.
Joseph Dunne was living with his family in Athy at the time, and decided to go to Naas that day with some friends.
As they were making their way home, the prosecution claims Mr Dunne hit Mr Almasi’s van, which led to the owner tearing out of his house armed with a baseball bat.
The jury heard it will be alleged that Mr Almasi struck Mr Dunne on the head with the bat, and that - despite the assistance of his friends, some people from a nearby restaurant and paramedics - he was pronounced dead in hospital shortly afterwards.
The trial is expected to take over two weeks.
