There are other hints coming out at the moment, such as an aside in the Panorama report on Savile last night by Merion Jones who's Aunt ran Duncroft girls school, which he apparently visited as a kid, describing it as.
wtf were celebrities and minor royals doing hanging around at an institutional residential girls school, particularly one where it now turns out that Savile was routinely abusing probably dozens of underage girls in the same time period.

There are also persistent comments from multiple sources about either the involvement or knowledge of MI5 in some capacity.
This is alleged to have begun in Northern Ireland at Kincora boys school in the 70s when a worker at the school who was also a loyalist commander as well as being a child abuser (eventually convicted) is alleged to have been an MI5 informant, with MI5 effectively blackmailing him with the child abuse evidence to force him to act as their informant, as well as using the school as a honey trap to give them dirt on other targets to force them into informing for them as well.
These allegations continue into at least the welsh situation, essentially alleging that again MI5 either used these homes as honey traps to get them incriminating evidence against people they wanted to force to work for them, or at least being aware of what was going on and choosing to use the evidence to gain them informants instead of putting a stop to it.
I've not really found hard evidence against MI5 on this, but this is a persistent claim that's been going on for 3 decades, originating apparently with a security services source who was then forced out for revealing it - it's been reported on by Private Eye, Scallywag and I think Channel 4 news at various points. In light of some of the other stuff the security services got up to in Northern Ireland in the pursuit of gaining and keeping touts in both camps, I'd say this part of the allegation is pretty credible, and if they did it there, it's fairly likely they'd have repeated the same methods elsewhere IMO.
It's worth bearing in mind here that similar situations have been exposed in recent years elsewhere in Europe, so it wouldn't be without precedent.
