Gardaí say their investigations are ongoing.
Gardai in Dublin have launched an appeal for witnesses after a man in his 60s was found in a critical condition in Swords.
He was discovered at about 2.30pm yesterday afternoon.
The man was found with serious injuries on a walkway beside the Malahide Road Roundabout.
