This is why in the past I have tended to shy away from those who play villains or generally despicable people. 9 out of 10 just want an excuse to be douche bags in game because they know there's no true authority to stop them.
On the other side, people in the role of assumed authority have the temptation to overstep their own bounds in the opposite way. The whole concept doesn't work unless the community respects the boundary of the character(s).
I have yet to threaten an arrest to anyone in game. I wouldn't do so either unless I spoke to the person in tells first to establish where they were trying to go with their RP at the time.
The only real thing you can do is call for help. Once the 'offender' realizes they are surrounded by people set against them, and potentially facing blacklisting by half the RP community if they don't comply, they will probably step down.
