Ms Nóirín O'Sullivan:

Again, this is a very complex and emergent phenomenon. It is very difficult to identify the perpetrators online. Cyber-bullying, in particular, is very insidious and people hide behind fake personas and pseudonyms. However, we have a unit that investigates that type of offence. We have a unit that is very focused on ensuring we build our capability and capacity to deal with it. We collaborate very closely on it, not only with other police forces and agencies but also with academia. We have a programme which involves University College Dublin to examine forensic computing and cybercrime, in particular. It is a growth area which we have identified as one of the emerging challenges with which we have to deal.
