My neighbour and her son sold us their house. They never lived in it and it was practically a ruin. She built a new build on land next door and they sold us the old ruin. We invested loads of time , money and energy and completely rebuilt it and now rent it out.
Since then we have suffered low level harassment from her son. He reported us to the council for our washing line and painting the house a slightly different colour beige than before ! He then broke our rain water storage and cut a hose pipe.
I caught him approaching our house another time with a metal bar and I confronted him , he behaved very aggressively poking the bar in my face. I tried to keep calm and just asked him what his problem was at which point he ran off with his fingers in his ears , dancing up and down like a young kid and behaving very strangely. He's 45 and holds down a job !
I reported it to the police but nothing was done.
I went into the house today to water the plants and noticed that a window was open. This window has no handle as it's a door length window with a drop outside and not safe so I never put a handle on it. Someone has climbed up from the outside, brought a handle with them ( the bar of which they have left in the door ) and entered the house. They couldn't shut the window from the outside so left it open. Nothing looks disturbed but I won't know if anything is missing till the tenants return. I am contacting the police but I have no proof it is him , though I am convinced it is. I contacted my tenants who say they have never opened that window and I have a photo taken a few weeks ago where I can clearly see that at that time the window had no handle bar.
WIBU to post him the handle anonymously so that he knows I know , and then if it wasn't him he will just think its weird and not connect it to me ? Given that his behaviour has been a bit unhinged in the past is it best to not get involved with him on any level ? How can I make him back off when I have no definite proof.
