If you are convicted of an offence where the court orders you to appear to have a sample of your DNA extracted and placed on the National DNA Databank, you will be given some paperwork and told to attend our police station to fulfil that requirement. If you are in custody (aka jail), we may bring you to the station before you go (back) to jail or we may visit you in jail to execute this order.
Once here, we will check to see if you already have had a DNA order executed in the past and if you have a DNA profile on the National DNA Databank. If so, we deal with the order differently (you won't need to provide a blood sample but we still have some fingerprints and paperwork to do).
If this is your first time with a DNA order, then you will be brought into our secure booking area where we read you some information, complete some paperwork, obtain a set of fingerprints and ultimately prick your finger and place some blood droplets on a collection card that gets sent to the National DNA Databank. The DNA profile created from your sample will be stored and compared against samples received from crime scenes (past, present and future) and if a match is found, we are notified. A match does not make you guilty of an offence, but simply indicates that your DNA was found in relation to the scene and will likely lead to some questions.
The process takes about 15-30 minutes and is very low key. You won't need stitches or a bandaid. Happily, you only have to give a sample once in your lifetime.
