I just think that when things are that bad with your neighbours, the best approach that almost always works is to try to restore a good relationship. GOing to the police and keep complaining to managmnet will surely make matters worse, I doubt it will get them out of their villa at all.

Sometimes is just best to knock on their door with a pie and a white flag and just work things out amicably. Besides, I always think there are two sides of every story.
