A teenager has been sentenced to seven and a half years in a Children's Detention Centre for killing 18-year-old Azzam Raguragui last year.
The 17-year-old boy, who can't be named because of his age, stabbed Azzam five times during a fight in a park in Dublin.
His trial heard the fight broke out over a stolen bike.
One witness described his friend, Azzam, being stabbed while he lay on the ground after slipping while being chased up a hill by the accused.
