Gardaí are investigating an incident during which a man was confronted by a group in South Kerry.
The incident which took place earlier this month was streamed online.
Gardaí say enquiries are ongoing and that the safety of children is their priority at all times.
An Garda Síochána says the actions by private groups and the manner of confrontation between such groups and their targets is concerning for them and other police services.
It says it has the potential for violence and could result in harm to those present.
An Garda Síochána urges anyone with information relating to the potential sexual exploitation of children to report it immediately to them.
