I posted a few weeks ago about a neighbour who had sent me a message about my children, complete with photo of the back of my house. I had lots of great advice and sympathy from you all, and I had the thread deleted while pending police intervention.
Update: Police agreed that she had crossed a serious line, especially following her previous damage, trespassing and theft of our property and the fact that we'd laid it out in text that there were boundaries and she was invading our privacy.
They sent a team round to speak to her and tell her to pack it in. The office who came over to see us said they would tell her that if she behaved like this again, they could reasonably arrest her for harassment. They were also going to quietly assess her for vulnerability or mental health needs.
We haven't seen her since, although we know she is there because she slams cupboards a lot. RESULT.
