I have absolutely no experience with this kind of thing, but it strikes me that this man sounds a little like an aggressive dog. If you can't reason with him, you can either confront him, or make him lose interest. By a confrontation you want to either shame him or scare him back, and both make him, in a sense, more "interested" in you, for lack of a better word. I'm not sure you want that level of attention, and it could make him want to get back at you somehow.
I'm not in any way saying you should skulk around and hide, but it may be that your best bet is making yourself "uninteresting". Either by ignoring him, if possible, or simply by removing yourself from his sight for a while so that he latches onto something else to do and forgets about his little "game".
But please do tell the police, and any neighbours you might have too.
PS. The quick-release on your wheel does not have to be on that tight. If you have to use a little effort - no leverage - to open it, that's plenty tight.
