I am being harassed at home, he bangs on the windows every morning

My old house has sat empty for a year thanks to covid. So I am there trying to undo a years neglect, and get it sold, but every morning he bangs on the windows, always incredibly early before I'm awake.

I rush to the window and he takes off. I have even run outside to confront him but by the time I get there he has already gone, or he hides in the bushes and is no where to be seen. This morning he started kicking the kitchen window while I was making coffee.

I don't really want to get authorities involved, I'd rather deal with it myself
