DS's ex has always had a history of dishonesty, helping herself to various family members' stuff, money etc. Not to go into detail, but the DGC have had a really raw deal from her and live-in lover. Lover used to work for the same bank that DS, DH and I use, and DGC discovered on their mother's phone a screenshot of DS's bank details - highly sensitive obviously, that he had accessed and sent her. Following DS's request for an investigation, which we requested also, as she has always had it in for us, for some unknown reason, despite all the help we gave them, we've just been told by the bank's privacy investigaors that Lover also went into our accounts with absolutely no justification. We are utterly beyond furious, the bank is helpless because he no longer works for them, but he is now with another industry now which deals with sensitive customer info. Is this a criminal offence or merely one that would be sackable/disciplined? If I sound incoherent, it's because I can't contain my anger. Thank you.
