I've looked into more news reports and this 'gang' are responsible for other attacks.
Why are the police sat on their asses! This happened early April - does it take Twitter sharing my horrified users to get anything done in Dublin? Come on Dublin authorities do your job and arrest these violent thugs.
"Gardai are probing if the same gang was behind two horrific attacks in north Dublin.
On the first occasion, CCTV footage showed a young female being pushed on to a train track at Howth Junction station on April 1.
The images showed a youth lunging at a woman before a pal attempts to use the wheel of his bike to trip her.
She managed to keep her feet but a second female - the 17-year-old - was clipped by the bike and fell into the gap between the platform and train.
As the thugs walked away, the shocked girl, who suffered minor injuries, was helped on to the platform.
In the most recent incident, a lad jumped on to the top of a family car after he was chased by 20 thugs in Malahide on Saturday night.
But he was later cornered by the mob and beaten before being treated in hospital for his injuries."
