An 18-year-old man has been remanded in custody after being charged with the manslaughter of Ryan Weir Gibbons in Kildare Town.
Ryan Murphy, from Curragh Plains in Kildare Town, appeared before Naas District Court this morning.
He was arrested earlier at his home.
The charge relates to an incident on 26th October, when Mr Weir Gibbons was found unresponsive on the Dublin Road and later died in hospital.
The court heard there had been an earlier exchange between both men on a bus.
Detective Sergeant Pat Dunne said Mr Murphy had been travelling with friends after a night out and that a verbal dispute broke out when Mr Weir Gibbons asked the group to quieten down.
Both men got off at separate stops but encountered each other again shortly after 3am, when an alleged altercation took place.
It’s alleged a single blow caused Mr Weir Gibbons to fall to the ground.
During a bail application, the defence said Mr Murphy will claim he acted in self-defence and noted he had presented himself to gardaí on the morning of the incident.
Gardaí objected to bail, citing the seriousness of the charge.
Judge Desmond Zaidan refused bail and remanded Mr Murphy in custody.
He will appear again via video link next Wednesday.
The court was told the accused recently completed his Leaving Cert and is studying in Carlow with the aim of becoming a rugby coach.
