Background check - false information?

I just got a great job with a huge company, and i have been working ther for about 2 months until, i got a call from HR saying they checked my criminal background and "they say", they found some convictions on my record, which i know for a fact is wrong, they have now sent me home with pay, pending an investigation, does anyone know the right paper work, i am supposed to show or get from the court, they say they have the same person with the same name and the same date of birth. but the information does not include my ss or dl. what do i do?
Answers:
You have the right to see whatever negative info they have. Then you can try to clear it up.

Contact the local police station or government building to get your records to show.

First of all though its worrisome it will probably turn out that it is no big deal. A huge company implies a trained HR staff and that training has to include this sort of situation. Plus the company that your company uses to do the checks has to have had this sort of thing happen before.
For one the odds that this other person lives in your same state are slim. So all it will probably take is for a real person to review the records instead of a computer. As far as your company goes I am surprised that HR has not apprised you of what the procedures are. Don't be shy about calling them as most people would be going crazy about this.
Another reason I am surprised is that I do know that in these cases they usually keep an employee up to date. Most companies figure out that it costs something like 25K all in all to hire somebody. Most would certainly not want you to start pushing out your resume. Plus they could be open to legal action.... hence why they are paying you.
I think the whole court thing would come later if need be. But you may consider being proactive. Call the police station and ask if they do background checks for a small fee as many provide this service. People get them for jobs as far as child care and security. Provide HR with this if you get one but it really shouldn't be necessary.
But it would help in the regard of if you lose your job for whatever reason (which probably won't happen) to have for later. You could sue a lot of people over this if it came down to it.
