Gardaí in Dublin have arrested three teenagers in relation to a violent disorder incident that occurred at a DART station last month.
The incident happened at Howth Junction DART Station on April 1st.
Videos of an alleged assault from that date went viral online.
They show a woman falling between the train and the platform, in an apparent attempt to dodge a group of teenagers.
The woman was rescued by onlookers before the train began to move.
Gardaí investigating the incident say three teenagers - one aged 13 and two aged 16 - were arrested today on suspicion of violent disorder.
They're being held at Clontarf, Raheny and Coolock Garda stations.
Five premises were also searched in north Dublin, with items including clothing, bikes and mobile phones seized.
