The teenager murdered following an altercation in Co Fermanagh has been named as John Paul McDonagh.
Detectives have launched a murder investigation after the death of the 18-year-old from Enniskillen in hospital on Monday morning.
He was injured during disturbances on the street in Coolcullen Meadow in the town on Saturday evening.
The PSNI said: “It had been reported an altercation was ongoing in the street involving a number of men who were brandishing weapons.
“Police attended the scene and found two men – including the man who sadly passed away and another male, aged 24 – who had sustained wounds to their legs and who were subsequently hospitalised.
“It is believed that another man involved in the incident had left the scene before officers arrived.”
A 19-year-old man was arrested and he has since been released on bail, pending further inquiries.
Detective chief inspector John Caldwell said: “Tragically, this morning, the 18-year-old male victim passed away in hospital and I want to express my condolences to the victim’s family, friends and loved ones at this very sad time.
“Our investigation continues this morning, and I am appealing to the public to help us establish exactly what happened and who was involved.”
