Sounds like you were detained and sent to the drunk tank until you sobered up. However, if a court date was set then you should retain a locally experienced criminal defense attorney ASAP.

I have a couple of thoughts. First, we can't give you competent answers to your questions without reviewing the police reports in your case, or at least talking to you. As a result, you'll need to consult with a local criminal defense attorney. Most of us offer a free consultation, so call around and hire the best one for you. Second, you've got this in the DUI section, but there's no mention to you driving or any DUI charges. You may want to change the practice area to public intoxication, unless of course you were arrested for a DUI. Good luck.
