GARDAI investigating the killing in Finglas of 29-year-old Vincent Maher in the early hours of Saturday morning have released two men who had been arrested.
Mr Maher (29), a father-of-one, died after being beaten to death at his apartment on Wellmount Road in the early hours of Saturday after a row over broken furniture in the flat.
Sources say gardai believe the victim was attacked after he confronted two men about the smashed-up furniture.
"The scene that gardai came across on Saturday morning was a very bloody one with a lot of broken glass -- there had clearly been a bad row in the apartment,” said one source.
"It was obvious enough that Mr Maher received a very bad beating. In particular he had some serious cuts on his head."
The investigation into his violent death has not yet been officially upgraded to murder.
Gardai are waiting for results of toxicology tests from Mr Maher's body to determine if the amount of alcohol and drugs in his system played a significant role in his death.
Gardai said it was possible that the victim would have survived if someone had called an ambulance.
Men were seen running from the apartment on Wellmount Road some time after 5am. His body was found lying beside his bed by a landlady who visited the flat at about 11am.
The two men in their 20s arrested in connection with the death were detained at Finglas Garda Station but released last night without charge.
A file on the case is being sent to the Director of Public Prosecutions.
Mr Maher was separated from his partner and his seven-year-old daughter was a regular visitor to his home in the Springmount apartments complex.
Gardai are continuing to appeal to anyone who may have attended a party in the apartment between 8pm on Friday evening and 7am on Saturday morning to come forward.
In addition Gardai would also like to speak to any Taxi drivers who may have collected passengers from the location to contact the Incident Room at Finglas Garda Station on 01-6667500, The Garda Confidential Line 1800 666 111 or any Garda Station.
