DH works at a university, I was also previously there for a number of years before 2021, so am familiar with the department. Their offices are quite big for postdocs, and during lockdown a new girl (X) started there. X's supervisor has a big research group and that's how she started being stalked by another postdoc Y. I don't know how it all started, but by the end of lockdowns when people started going back to the office it was already such an issue that DH knew about it. X complained to her supervisor who told Y to stop writing handwritten letters, and he just started sending emails.
Then Y's contract expires, he gets a postdoc in another city 3h away, yet travels back once a week for 'lunches with the group'. This goes on for about 2 years, in which time X gets a position in Europe and leaves. Meanwhile, the supervisor knows about all of this, the department admin people get forwarded emails Y now starts sending to my DH (and others) about X. Yet, Y is hired AGAIN by the supervisor just as X leaves for Europe.
I don't know whether X filed a formal complaint to HR about Y... I was in a bit of a similar but less wild situation at the same uni, I filed a complaint and the guy got a telling off from the School and I was also told that when he's looking for a job and wants an HR reference - they will say they have no comment about him, which means there's basically nothing good. So the fact Y got hired AGAIN is just shocking to me. I think X's ordeal with Y is like tenfold what I experienced...
Anyway, is there anything I can do? X comes back for work trips and Y just goes insane, I've seen the emails, it seems it's escalating... last one Y was 'filled with fury' that X didn't show up to a 1-1 meeting they supposedly arranged (although I'm a bit sceptical of the truth here). All emails get forwarded to School admin... Don't know why X hasn't done HR complaint about him, though I now think a restraining order is more appropriate... it might be cultural, like formal methods of complaint might backfire in country of origin. Y is British citizen, X is non-UK/non-EU but works in EU. I've seen emails where Y is basically threatening that 'his associates will give [X] a visit' (??). Idk if X forwards such stuff to admin, but anything DH receives I ask him to forward. They've even got a whatsapp group to document all of it, and X has expressed she's worried Y will come and k*ll her one day, in a non-joke way. Surely that's enough...?
I realise I'm not the one being harassed here but is there anything I can do? Filing HR complaint on X's behalf is possible but on the page it says no action will be taken if I'm anonymous. Uni has a security service, can I make them aware?
