Gardaí in Dublin have arrested an additional teenager in relation to an incident of violent disorder at Howth Junction Dart station on April 1st.
Videos of an alleged assault from that date went viral online and show a young woman falling between the train and the platform, in an attempt to dodge a group of teenagers.
Investigating officers had previously arrested three teenagers in connection with the incident following a number of searches on the morning of May 13th.
During the course of these searches in north Dublin, gardaí seized clothes, bicycles and mobile phones. Two of the teenagers arrested at that point were 16-years-old, while the third was 13-years-old.
A statement from Gardaí confirmed the juvenile arrested on Tuesday was detained at Raheny Garda station but has since been released.
A file is now being prepared for submission to the Director of Public Prosecutions and investigations are ongoing.
