That Surrey Police is investigating does not mean that much, they're pretty corrupt, like just about every police force. They have a tendency to 'investigate' and you sit back and relax, thinking, okay, they're on it. Time passes and nothing comes of it, 'not enough evidence to proceed' but the story has died down by then, that's the idea.
They do this with allegations against care homes for the elderly. I took a story about Firtree House Nursing Home in Banstead to the press, the police said they were 'investigating' but they never phoned me!
Years ago there was a story about historical sexual abuse in a Banstead care home in Firtree Road (I happened upon it while Googling my own story at a different care home in that road), you can find it on the net still probably. Victims were encouraged to contact a legal firm with allegations. This and some of Savile's goings-on in a Nork young people's home were also a thing, but nothing has come of it and one suspects people were encouraged to come forward so they could keep tabs on the story and delete any relevant files, to contain it.
Lord Mountbatten was accused of sexually abusing kids in a Northern Ireland care home, it is documented in Andrew Lownie's biography some years ago, 20 pages is devoted to it. Lownie did the recent bombshell account of the Duke and Duchess. The press has largely ignored the stuff on Mountbatten and there's been no investigation - admittedly this took place over half a century ago.
(I wrongly posted this earlier on another Andrew thread, sorry for the duplication, I can't delete the other one.)
