A teenager in Dublin has avoided a prison sentence after an incident which saw a 17-year-old girl falling head-first under a DART train.

It happened at the Howth Junction station on April 1st last year.

The 17-year-old boy, who accepted his presence was intimidating, was released on six months of supervised probation.

The prosecution had video footage from the station's CCTV system, a security guard's bodycam, and evidence from a second teenage girl who interacted with the group.

The group, about 10 in number, were put off the train due to anti-social complaints.

One of the 17-year-old boys swung his foot at a girl from his bike, making contact with her head.

The victim described the incident as daunting and that "one of them lunged" at her.

The court heard they were identified by Gardaí after confidential information from the public.

Judge Paul Kelly said there was a clear threat of violence.

A teenager had a six month probation imposed.

While sentencing for another teenager, who swung his foot at the girl's head, has been adjourned for another month.
