Wow what a pervert 💀
So I would recommend calling providing sources (like the police [which you already did]) and i also would write down what he looks and sounds like so the police can find him through traits easier

Also make sure to secure your establishment so he can’t go in, lock all doors and windows so that horny fucker can’t get in

Also keep a weapon handy if the situation escalates further :)

And I'm terrified

I'm being stalked and I saw him out the window of my house
