We got new neighbours behind us 2 years ago, the guy approached us to ask if he could have his gardener cut the height of our trees. We purchased our property with one the benefits being the mature trees and we regularly maintained them (compared to the other neighbours beside us, ours aren't as tall). We told him we were happy with our tree surgeon and that we got them cut regularly as it was, we were content with this arrangement and that we valued our privacy (they cover the view into our bedroom windows).
He then approached us again 6 months later asking the same thing and asking my oh to go into his garden, we were not happy with his insistent approach, but politely wrote a letter confirming what we had told him before and attached a photo of our trees from our garden.
He then cut the trees in his garden and at the time probably thinned quite a few of ours within our boundary, but we let it go. Now 2 years later, he has cut the top off one of our trees definitely in our garden and our neighbours behind can now see into our bedroom. If the tree would grow up again, I wouldn't have said anything but I was informed it won't. I felt very angry at what had happened and annoyed he hadnt listened to us, not to cut the trees in our garden so I went to the police. The went round and had a chat with him and he said he didnt do it, it was his gardener, etc.
We then tried to put up a new fence within our garden and he came and threatened our handymen. Nothing has happened since thankfully but our fence was left unfinished and I'm regretting going to the police as I've made our house harder to sell. Is there any way I can solve this? Did I do the wrong thing?
