Looking for some advice for my DGM.
GM lives in a block of 6 flats (opened by 1 LL) which is privately rented (not social).
Since COVID-19, one particular neighbour has taken it upon himself to police the flats and it's post. I'll refer to him as X.
Each flat door has their own letterbox but since covid, X will not let any posties into the building, bullied them away and demands that they leave all post in a basket in the community hallway. X will then deliver the post himself when he sees fit.
This is a huge concern private and confidential post it lying in a basket for anyone else to grab.
X has also taken it upon himself to police who comes and goes into the flats. He's put up posters on doors and walls stating that under Government Guidelines, no visitors are allowed into the building and residents are not allowed to leave to visit other households. Which is completely wrong, not that it's his place to enforce any rules.
Whenever my DM goes to see GM, he harasses her. Saying how she shouldn't be there blah blah blah. My GM and other elderly residents feel completely intimidated, harassed and isolated.
Now X WAS the building care taker but was sacked after a falling out with the LL. He is not the LL (not that a LL can dictate visitors) and he has no right to be putting up posters and policing what others are doing.
What can we do here? He is not rational and cannot be reasoned with. Is this a matter we can raise with the police?
