12 yrs ago I got into a bit of trouble because of a small theft from an employer. Realised afterwards that there was no proof, but I was so scared and bullied into confessing by my employer that I admitted it and received a police caution. I am now 29 and would like to help out at my sons beavers group. I have filled in a CRB check which only asked if I had any unspent convictions. To this I said no as a caution isn't actually a conviction, just a warning. I'm sure I was told at the time that the caution would last 3 years. What will come back on the CRB, how much detail will be given and how likely is it that I will be able to help. Thanks.
