It is with regret that I write on behalf of the bank to inform you that vaults within your possession have been entered illegally by unauthorised person, or persons unknown. I must offer my sincerest apologies for this lapse in security. With a long history of safely guarding the wealth of the wizarding world, Gringotts Bank takes such matters extremely seriously, and has liaised with the proper wizarding authorities (as required by law) but will also be launching a private investigation in order to bring the perpetuators to justice. I would like to assure you that, though the Bank is required to inform the authorities of this break in, Bank policy prohibits the disclosure of your identity without your express permission.
