A man in his 50s who was arrested after a serious assault in Dublin yesterday has been released without charge.
The investigation began after a man in his 70s suffered serious head and spinal injuries in the incident, which occurred at around 2am on Saturday morning at Courtney Place in Ballybough.
The victim had been returning on foot from a night out when it is believed he was assaulted in the stairwell of the flat complex.
He was taken to the Mater Hospital where he is continuing to receive treatment tonight.
A file will now be prepared for the Director of Public Prosecutions.
Gardaí are continuing to appeal for witnesses to contact Mountjoy Garda Station on 01-6668601, the Garda Confidential Line on 1800 666 111 or any garda station.
