What can I do if I suspect a person I know - an acquaintance is impersonating me via email. I have received information that about a request for to access my medical records, which I did not, but have been shown evidence of the email I allegedly sent, at the time the email was sent, I was in hospital having surgery and unconscious under anaesthetic. I would have thought this would be a matter for the police, but I cannot prove it, only suspect it.
