A young man died last night after being stabbed in south Dublin.
Gardai have begun a murder investigation into the death of the 19-year- old who suffered stab wounds in Finsbury Park, Dundrum.
It is understood the incident happened at about 8.10pm yesterday.
The teenager was treated at the scene by emergency services and was rushed to St James's Hospital.
However, despite efforts to save him, he was pronounced dead a short time later.
The vicinity of the park was sealed off pending a garda forensic examination and an incident room has been established at Dundrum Garda Station.
Churchtown councillor Shay Brennan expressed his shock at last night's tragedy.
"To hear that such a young man lost his life in such a violent way is absolutely devastating," he said.
"No one had ever expected something like this to happen.
"My thoughts and prayers go to this young man's family."
Dundrum councillor Brian Murphy told the Herald that violent attacks are unheard of in the locality.
"I'm just completely shocked that someone so young has died like this," he said.
"It's very tragic, and while we wait for the details and circumstances of this crime to emerge, I can only offer my thoughts and sympathies to this young man's family and friends.
"I'm sure the community will be there to support his family during this very sad time."
