A man who is on trial for murder told an investigating garda that he got a baseball bat and followed a man who had damaged his car outside his house.
Zoltan Almasi, 44, with an address at Harbour View, Naas, Co Kildare is charged with murdering Joseph Dunne at the same address on 16 May 2014.
Last week at the Central Criminal Court, Mr Almasi, who is Hungarian, pleaded not guilty to murdering Mr Dunne.
Today, Garda Stephen Flaherty of Naas Garda Station told the court he arrived at the scene at Harbour View at 10.20pm on the night in question.
He said he saw a male lying on the ground with a few people around him.
The court heard he had been given a brief description of the alleged offender at the scene.
Gda Flaherty said Mickey McDonagh, a friend of the deceased, had pointed out a house at Harbour View, indicating that the suspect had returned there.
The court heard Gda Flaherty called to the house but "got no response".
He then returned to preserve the scene before he was approached by a man at 11.20pm.
"The male was looking to go towards the initial house that was pointed out to me. He matched the description of the alleged offender for the assault," said Gda Flaherty.
The court heard that when Gda Flaherty told the man he could not approach the house he turned to leave the area.
"I requested the male to come back to me," said Gda Flaherty.
When this man was asked for his name and address, he gave the name of Zoltan Almasi with an address in Naas.
Gda Flaherty then asked Mr Almasi if he had witnessed anything.
The garda said Mr Almasi told him: "I came home and parked my car behind the garage. I went into the house and heard bang, bang, bang.
"There were four guys and one girl outside my house damaging my car."
The court heard Mr Almasi said he then came out of his house with a baseball bat and followed one of the men who then "fell to the floor".
Mr Almasi was arrested at 11.19pm that night and brought to Naas Garda Station.
The trial continues.
