An 18-year-old man and woman remain in custody having been arrested last night following a fatal stabbing incident in Dublin. 

24-year-old Paul (Paulie) Curran was stabbed and fatally injured in a stairwell of the Seagull House flat complex on Rutland Avenue in Crumlin at around 4pm. 

Today a post-mortem examination was to be carried out and garda forensics have re-examined the scene of the crime. 

Local Sinn Féin councillor Ray McHugh condemned the attack.

He said his party had put a request in to the Minister for Justice Frances Fitzgerald for more gardaí on the street, by employing civilians in garda stations.

Mr McHugh said he knew the victim when he was younger, when Paul played in the Youth against Drugs football tournament, organised by Mr McHugh.  Paul also managed teams when he was slightly older.

Paul Curran's brother, David Curran, is serving life in prison for the murder of two Polish men with a screwdriver.  That attack happened in Drimnagh in 2008.
