I'd like to think that the operator themselves are investigating these events...like their Safety Management System should lead them to do. I would expect any aircraft operator to treat every incident as an independent event in the first instance (to avoid confirmation bias, if nothing else) and for the investigation to identify any common causal or contributory factors, which, if there are any, means that the events are not, in fact, independent. To jump to conclusions on the basis of the level of analysis suggested in the original post is unwise.
Yes, one would expect the local regulator to take a look - ideally to see that the operator is correctly assessing the situation themselves. But with the three event all occurring in EASA-land, why not ask EASA to investigate? It is, after all, one of the reasons for requiring reporting from all member states and for setting up a central repository...you know, to identify trends which are not evident within a single State.
