A bit puzzled and confused about this.
I subscribe to the update service for the DBS. Received this letter.
As part of your subscription we continually check the police national computer (PNC) and have found the record of a person with similar identify details to your own. This does not mean that this PNC record belongs to you, however, we need to confirm that this is not the case. To do this, we need to compare your fingerprints with those held on the PNC record.
There is more, but that’s the important part.
I know everyone will say scam but I’m as sure as I can be that it isn’t. Completely baffled and not entirely comfortable with it.
