A man who attacked a suspected burglar in his home in the early hours of Sunday morning brought the man to hospital and reported the incident to the gardaí.
The man heard a noise in his home at around 2am and saw another man in his garden.
He went out and challenged the man who appears to have told the resident that he was not alone.
The resident then appears to have got a weapon and the suspected intruder was struck on the leg.
The victim in his 30s was seriously injured and the resident took him to Tallaght Hospital in Dublin 24.
However the victim appears to have discharged himself only to be subsequently admitted to the Mater Hospital in Dublin.
The homeowner then reported the matter to the gardaí who are now investigating the incident.
The victim sustained serious injuries to his leg and underwent surgery yesterday.
Gardaí are waiting to interview him but it is not clear if he will make a complaint.
He is known to gardaí and the drug treatment services.
Residents and homeowners are legally entitled to defend themselves and their families in the place they live.
Under the Criminal Law Defence and Dwelling Act (2011) it is not an offence for a lawful occupant in a dwelling to use force against another person to protect themselves or another person, if the force is reasonable and if they believe the person has entered the property as a trespasser to commit a criminal act.
Gardaí have confirmed they are investigating “an alleged assault at a residential premises in Fettercairn, Tallaght, Dublin”.
They said “a man is being treated at a hospital in Dublin for serious injuries”.
