At around half 5 yesterday evening a 14 year old boy received a head injury during an incident involving a large group of teenagers at Kilbarrack Dart Station.
While ambulance personnel treated the boy's injuries, they came under attack by the gang.
Gardaí intervened and were assaulted by the group.
Two boys in their mid teens were arrested at the scene. The injured teenager did not require hospital treatment.
