Some seriously excellent advice on here IMHO so only one thing I would add...

He must be taught to understand that there are consequences for his actions, we all have them but how you go about it I wouldn't like to suggest not having witnessed his behaviour patterns personally.

Looking at previous posts in this thread it looks like all the options are laid out but only you can choose what you believe is the correct method.

I wish you and your son every success in the days ahead.
