Gardai have released a man they were questioning about a fatal stabbing in Tallaght on Saturday, February 18th.
A 32 year old man died after he was knifed at a house on Deerpark Avenue. He's been named locally as Graham McKeever.
The dad of one was found unconscious outside the house by emergency services at around 4.40am. It's understood he'd sustained a number of knife wounds.
His body was taken to the City Morgue in Whitehall where a post mortem was carried out and special detectives conducted a technical examination of the crime scene.
A suspect in his early 40's was arrested Sunday evening in connection with the attack.
He has since been released without charge and a file is being prepared for the Director of Public Prosecutions.
