AIBU to think this intimidating house buying letter should be reported to police?

[Blopi]

Friend’s elderly neighbours came back from holiday to find a letter delivered by person. It has made them upset and frightened.

It was addressed to them personally Mr and Mrs (surname)
They said that their home is too big for the couple and would be suitable for a 5 bedroom HMO. Willing to pay £Xk for it (properties have been selling for 10-15% more) and will visit them on Thursday at 11am to discuss things. Signed by Mr (common surname). No phone number or email address.

Her neighbours have zero intention of moving home as they have lived there for 58 years. They are upset on how they are targeted and wondering how did they get their names?

In the past I had these letters which have been sent to others down the estate. Though not intimidating like this letter, nor personalised.

Unfortunately my friend is working on Thursday. She would have loved to have seen if the person turned up and told

Should my friend phone the police on the non emergency line about this? As maybe something else dodgy going on

Well at least you're honest in this instance, but what did you expect the police to do?

Everyone suggesting having someone at the house? You must know people with tons of spare time...you know there is an option of just don't answer the effing door! People go away after 3 mins if you ignore them.

Phone the Police - no option.

You must know people with tons of spare time
I could do this to help out a neighbour but I don't have 'tons of spare time', I just work at home and would do it in lieu of a lunch break. I'm sure I'm not the only one.

I'd do this for a neighbour. Additionally several years ago I had a weird episode with a random caller offering to do DIY for me and tried to enter the house. He was definitely strange, might have been high and when i said no and shut the door, he stole my wireless doorbell push...it was amazing the distance it would still operate over!!

Anyway I posted on local SM to warn others and got several messages back asking if I was ok and did I need someone with me which I thought very kind. Several other people posted that he had appeared at their doors and due to this "tracking" the local police were able to pick him up. Obvs i never heard the end of the story.

Fuck me, you’re persistent! 🙄

Yeah ok, you know lots of things about the police. Happy now? Because it is too fucking hot to argue about something that didn’t even happen in the end.

Name they would get from electoral register . I’d make sure someone was there on Thursday in case they showed up and told them to fuck off also gim it on a phone.
I’ve had these and ignored it . Someone wanting a property but not willing to go through proper channels or pay full price.
mid your friend did want to sell hopefully they will go through a proper estate agency and lawyer . Not some we buy any house asshole

Any mileage in calling age concern for some advice
