Hi worrier. Interesting question.
Eddie// The first investigation will be by the medical council , only if they come up with strong enough evidence will it get handed over to the police.
Most cases like this never get to the police the Medical council can suspend or strike off a doctor and impose fines without involving the courts/police. //
Nope or well not really. The GMC is about registration and being a registered doctor, and they should be informed ( really by your sister ) of her allegations. They are bound by law to investigate all complaints. They will have records of anyone else complaining about the Dr ( Dr X say ) . They say they have all sorts of functions but being an investigation and filter unit for the Police even they would say 'no'
She should also complain to the Police - actually the quicker the better.
AS for advertising - - it depends if you believe your sister or not.
And if you do, then you should advertise.... but I am not sure if any newspaper would take the advert. Libel is an obvious danger.
You could offer to indemnify the paper in the event of proceedings but I dont suppose you have that sort of money. Perhaps talking to a reporter is a better idea.
Altho Vanessa F popped up on tel and said o I was assaulted,
you can see it is not easy to get these things started.....
