The incident happened in Avonbeg Gardens on Thursday evening
Police are trying to establish a motive for the murder of a man in Tallaght, Dublin.
Karl Holmes, 44, from Homelawn in Tallaght, was attacked and beaten during a row in Avonbeg Gardens on Thursday evening.
He was seriously injured and later died in hospital.
Police believe a group of people were standing outside houses when a row broke out at about 17:30 local time.
RTÉ reports that more people, including Mr Holmes, became involved and the row escalated and became violent.
Mr Holmes sustained several blows.
He was taken to Tallaght Hospital but died there about an hour later.
An incident room has been established at Tallaght Garda Station and house to house enquiries are ongoing.
A post-mortem examination is due to take place later at Tallaght Hospital.
Mr Holmes had criminal convictions for a number of offences, including breach of the peace and public order.
In 2009, he was sentenced to a year in prison for defrauding the revenue of more than €50,000 (£36,600) as part of a construction scam run by professional criminals.
He was also jailed for five years in 1994 for grievous bodily harm.
