Two men in their twenties have been re-arrested on suspicion of murdering a man in Tallaght.
Vincent Parsons died in hospital two days after he was found with serious head injuries in Killinarden in August.
Gardai believe the 34-year-old from Clondalkin was attacked near a nearby pub.
Two men in their 20s were arrested last month in connection with his death, but were released without charge.
However, they were re-arrested this morning on suspicion of murder.
They have been taken to Tallaght Garda Station, where they can be held for up to 24 hours.
