Detectives are poised to launch a murder inquiry after a 63-year-old man died almost a week after being viciously beaten.
A post-mortem examination will determine if the investigation is to be upgraded.
The man, named locally as Martin O'Gorman, a bachelor from Athlone, was found unconscious by a taxi driver on Academy Street in Navan, Co Meath, at around 12:30am last Monday.
It is believed he sustained head injuries during a serious assault by a group of up to four people.
He lost his fight for life at Beaumont Hospital, in Dublin.
Mr O'Gorman's wallet, cash and mobile phone were found on him after the assault, leaving investigators confused about the motive. No-one has yet been arrested over the attack.
The victim, who was known as a Meath GAA supporter, was initially taken to Our Lady of Lourdes Hospital in Drogheda before being transferred to Beaumont.
It is believed he had been socialising in Navan after the Meath v Laois GAA match in Tullamore.
Investigating gardai have renewed their appeal for information.
Supt Michael Devine of Navan Garda station said they were seeking to speak to three or four people, at least two of whom were women, seen around Academy Street between midnight and 1am on the night of the assault.
