Why / how are you asking?
If you are the victim then you file a complaint with law enforcement and if they can tie an individual to a criminal act then they can make an arrest (either physically or by "notice to appear").
If you are the subject then someone else files a complaint with law enforcement and if they can tie you to a criminal act then you can be arrested (either physically or by "notice to appear").
I hope this has been helpful to you.

Fourth: Anything that you post on Avvo (or on similar sites) or on any social media is by its nature public. It is essentially an admission / confession and can be introduced into evidence as a statement against your interest in a subsequent legal proceeding.
