Looks like 1960 Act still applies, from the Surrey Police report into their investigation regarding one of the allegations at Duncroft...
Police have confirmed via the CPS Head of Trials Unit that the only relevant offence that may have been committed was under S.1 Indecency with Children Act 1960. However, this offence is only applicable if committed against a child under the age of 14yrs therefore it is reasonable to conclude Ms D was not a victim of crime in the event she describes. She was of course a victim of Savile’s inappropriate behaviour.
Might explain why historic cases featured in the press are of people said to have been 14 years old at the time?
