The parents of a teenage boy who was stabbed to death in a park have said: "We are resting our faith in the Irish justice system."
Azzam Raguragui (18) was fatally stabbed last Friday night in Dundrum following a row in a local park.
His devastated parents Abderrahmane Raguragui and Hajiba Elouaddaf thanked the public for their support and said they are hopeful that those responsible for their son's murder will face justice.
They said in a statement: "The past few days have been very difficult and challenging for our family.
"An Garda Síochána is leading in the investigation to uncover the truth behind our son Azzam Raguragui's murder and we are resting our faith in the Irish justice system to hold the perpetrator(s) to account.
"We are grateful for the community support we have received. At this critical time we would like to request some space and privacy to allow us to grieve as a family."
Azzam has been described as respectful and cheerful, and was due to attend evening prayers in Clonskeagh Mosque on Friday.
Detectives have launched a murder investigation and have ruled out a racial motive. Gardaí have spoken to a teen who is the chief suspect in the killing.
This boy, who is from south Dublin, has claimed that he acted in self-defence when he fatally stabbed Mr Raguragui.
A source said the boy presented to gardaí on Saturday with a legal adviser and a prepared statement.
"No arrests have yet been made and a juvenile teen is continuing to assist gardaí with their investigation.
"This is a very sensitive investigation, given the young ages of the people involved," a senior source said.
Gardaí have spoken to a number of people in relation to the murder but are continuing to identify everyone who was present on Friday.
