Three teenagers arrested over an incident in Howth Junction Dart station last month which resulted in a young woman falling onto the tracks, have been released without charge. The criminal investigation into the incident is continuing. Gardaà investigating the violent disorder believe they know the identities of most of the young people who were on the scene at the time but they have appealed for anyone who was present to come forward for interview. Two of the boys arrested on Thursday during early morning searches at their homes are aged 16 years, while the third boy is aged 13 years. They were taken to separate Garda stations in north Dublin and held through Thursday for questioning before being released without charge.
