Gardai are warning so-called paedophile hunters not to take the law into their own hands.
It comes as Gardai investigate an alleged assault on a man in Ballyfermot in Dublin yesterday.
This man was allegedly attacked after being confronted by a vigilante group.
Gardai say the actions of such groups are a cause of concern as they could encourage violence.
They could also affect future criminal proceedings.
Louise live-streamed yesterday's confrontation, and explained why she decided to do so:
Do we condone violence? Absolutely not. If we condone violence we wouldn't be going live and dealing with them ourselves. We have over every bit of evidence to the Gardai.
