A man in his late forties is in serious condition at Beaumont Hospital after an attack in Telaght Saturday evening.
A man was found unconscious with head injuries on a playground at the Mac Uilliam estate, Tallaght, around 11.40pm by Gardaí and emergency services.
He was taken from the scene by ambulance to Telagh Hospital but has since been transferred to Beaumont Hospital where his condition is understood to be serious.
The scene is currently undergoing a forensic examination by the police technical office, and no one has been arrested so far in connection with the assault.
Gardy pleads eyewitnesses in particular to those who were near the ballpark at the Mac Uilliam property late last night to come forward. They also appeal to those who have video footage (including a dash cam) to make it available to them.
Anyone with information is asked to contact Tallaght Garda Station 01-666 6000 or Garda Confidential Line 1800666111.
