Sounds a bit strange for a white to be dealt in such a manner. Looks like you went overboard with the fighting and ofcourse being drunk. Maybe you slammed some important chap or his son. I would suggest that you go to your embassy and see what happens.

As for rights you have none. Up to you to suck it up and stay or leave. You will lose more by going against anyone.

For starters did you get yourself admitted to a hospital as soon as you were released?? because proof of the cause of the broken bones lies with you.
