If you would like to go down the official avenue of applying for an arrest warrant you can download the form here: Application for Arrest Warrant. Feel free to complete it in any way you wish. Your next step is to send it off to a Justice of the Peace. We’d recommend recorded delivery. You can find your local Justice of the Peace or Distric Judge here.
There may potentially be an easier path, you could report the offence(s) to your local police station. Don’t hold your breath though.
