In 1989 and 1997 I was convicted of theift and fraud. Both times recieved fine and community service order. I have recently applied for an enhanced disclosure certificate and it has no record of either conviction on it. I have was honest when filling in the forms and gave all the correct details ref addresses etc. 

Because there was nothing on the DBS I did a subject access request to my local force and they told me there are no records of me ever being convicted of anything on the National Police database.

How can this be??

Cheers
