Two men are still being questioned by Gardaí in relation to the suspicious death of Vincent Maher in Finglas in Dublin on Friday night.
The body of the 29-year-old was found in the bedroom of his apartment on the Wellmount Road on Saturday morning.
It is understood he suffered a violent death and details of a post mortem are not being released for operational reasons.
Gardaí are appealing for information.
In particular, they want to speak to any guests at a party at the apartment on Friday or any taxi drivers who dropped off guests.
