This is my first post on this forum, so expect me to get it wrong.
If your neighbour is a persistent nuisance, it might be a good idea to report the matter to the Police. Criminal damage is a crime, and although it probably would not be worth doing anything this time round, reporting it would at least help in the event something else were to happen. Likewise, maybe talking to the local Council's Anti-social behaviour Officer and perhaps registering the situation with them. Whatever you do, I would advise you make a note in your diary (the time and what was said etc) and note anything else that happens or is said between you from now on.
