Gardaí in Dublin have arrested three youths in connection with a violent disorder incident in which a girl fell underneath a Dart train.
The incident occurred at Howth Junction Dart Station at 9pm on April 1, though a video of it only recently began to circulate on social media.
In the video, which appears to have been captured via CCTV, a number of passengers are seen rushing towards a stationary Dart train.
A group of youths, some of whom are on bicycles, can be seen standing on the middle of the platform and intimidating the passengers running to catch their train.
One youth lunges towards a girl who, in her attempt to evade him, trips over another's bicycle and falls into the space between the platform and the waiting train.
Some of the group leave the scene as Dart security and a group of other train users quickly help the girl out from under the train and back onto the platform.
The severity of the injuries the young woman sustained is not clear.
Gardaí said they began a search operation this morning across North Dublin at five locations on foot of warrants issued pursuant to Section 10 of the Criminal Justice (Miscellaneous Provisions) Act, 1997.
During the course of the searches, a number of items of clothing, as well as pedal cycles and mobile phones were seized.
Three youths (two aged 16 years and one aged 13 years) were arrested on suspicion of violent disorder under the Public Order Act, 1994.
All three have since been released without charge.
Gardaí said their investigations were ongoing and are appealing to those who were present at the time of the incident or to anyone who can assist in this investigation to come forward.
