That is absolutely terrifying. And the cell phone video should be good proof for the police.
There is also an ABB "Blacklist" group on Facebook. (you should be able to find it via search) So maybe consider posting his profile there, in case ABB does not remove him from the platform.
I'm so sorry this happened. I'm a female who lives alone, too, and I can't imagine how violated you must feel.
Formal complaint definitely! They may not be able to charge him with anything, or whatever. But the important thing is there's a record. So if it happens again, it can establish a pattern and make the next claim more believeable. (as sad as it sounds to write that a single claim might not be believeable)
