As recounted by you the facts suggest multiple violations of your 4th Amendment rights. I say as recounted by you because you can be fairly confident that the account provided by the officers will be substantially different. Securing legal counsel now would be a very good idea. There may be evidence available to help corroborate your account, but that needs to be investigated by a knowledgable criminal defense attorney right away. Do not post anymore details anywhere on the Internet, including social media like Facebook. Start interviewing lawyers for the job of helping you make the best of an unfortunate but not uncommon brand of policing. Good luck.
It sounds like you may have a strong case to have the evidence thrown out as "fruit of the poisonous tree." If you can come up with the funds, hire a local defense attorney right away.
Sounds like you may have a good motion to suppress. Consult with a local criminal defense attorney immediately.
