Frances Fitzgerald (Dublin Mid West, Fine Gael) | Oireachtas source

I will reiterate the kinds of circumstances about which we are talking. A condition of bail is imposed on the accused person. There are grounds to reasonably suspect that the person is about to breach that condition. Immediate arrest is necessary to prevent harm to, or interference with a victim or a witness. A condition is imposed in the first instance, there are grounds to suspect that the person is about to breach the condition and immediate arrest is necessary to prevent harm or interference with a victim or witness. If all these circumstances do not exist then there is no power of arrest.

I think an arrest without warrant in such circumstances, where it is necessary to prevent harm to someone, is absolutely reasonable and justified.
