First off, I hope if you were arrested and charged with an offense, you reported it to your CoC right away. Why??

Depending on the charge, whether or not you are found guilty (very important), etc, you may/may not have 'career implications' placed on you.
If you are in the CF, and have been charged with something, and you haven't disclosed to your CoC, I suggest you do so immediately.
Without details of the charge, etc, I doubt anyone here can give you a solid answer.
