No way to tell with out investigating. You should call the jail where you were detained and see whether you were fingerprinted. That should clear it up pretty quick, if they fingerprinted you, the FBI probably has it. You also could do a background search on yourself to see it it pops up.
Not sure if anyone here can answer your question. If you are happy with your lawyer and he/she handles personal injury cases then why would you need to find another one? Is a reason why you would feel more comfortable asking a public forum than your Attorney first?
