Important thing to mention we’re in the EU, not in the US.

So basically the above. Won’t dox myself but there are pictures uploaded with the names of the women, the pictures were taken in private, some of these pictures were taken when my girlfriend was alone with the person. There are also a lot of pictures of women taken secretly. There are also details mentioned about e.g. the flats of women or other details that you can only know if you know the people. There also photoshopped pictures where throats are slit and there are very explicit murder + rape fantasies written out.

Right now we have two possible explanations

1. It is the person we suspect it is
2. Someone who knows the person and is part of our friend circle has hacked the iCloud of the person we suspect it is.

Besides going to the police is there anything we can do about this? My fear is that our national police is too incompetent to deal with this.
