Is it possible for you to knock on his door and ask if you can have a talk to him? - to find out what is bugging him. You say he has been a long term friend, but has turned nasty - for some reason.
He may be upset about something you haven't thought ot. It does seem that it is alcohol-fuelled, but that's when the real reason surfaces - so I would be making sure you have the right reason for his nastiness before you take the matter any further.
I do agree that you would be better off not sharing the internet - but that may not have anything to do with his attitude.

Thanks.

It's based on tried and tested methods. I have never met a case of antisocial behaviour without an underlying "personal well being" cause unless it is drug related.

It's such a shame when relationships break down - without a clear reason.

Sounds like harrassment to me. You need to be prepared to tackle to matter as it sounds like it has been getting out of hand.

The Police could issue a Harrassment Warning to him if his behaviour continues if you can show it has happened two or more times. That normally resolves the problem. Have you got two or more screen shots that he has sent you?

Contact Environmental Health when you have established a pattern of his behaviour. An Officer could place a noise abbatement order on the Land Owner (assuming its him) or place the duty of care on his Land Lord to prevent Anti social behaviour (Section 21 Housing Act) - if they wittness Statutory Noise Nusiance. A "Dat Recorder" can be used if it is happening during unsociable hours and the Environmental Protection Officer works up to 01:00.

Libby, don't know where you live but I wonder if you have a local branch of Unite that may be able to help? This is a voluntary mediation service that assists in neighbour disputes.
However, at the end of the day, sadly, you may just have to accept that there's nothing you can do until your neighbour agrees that there is a problem that needs resolution.

Mediation is certainly another option.

It doesn't always mean that both sides have to sit down at a table - but it works better if they are prepared to. The mediator can relay information on your behalf to your neighbour. Restorative Justice is very successful. Showing how their behaviour has been affecting others - and offering a path to make up.

How are things going ?

It really doesn't sound as if this man will be open to any approach as he has a drink problem. Personally i think you wont get back to the way it was before so will have to accept he has a problem that only he can move on. In the meanwhile you have to protect your immediate family so if it means getting the authorities involved thats what you have to do .Leaving it to sort itself out really wont work and will only cause more aggro for your family.
There really has to come a time when a line has to be drawn!!
