I suspect the daughter's friend revised her age downwards after getting the green light from the Savile allegations. She was supposed to have considered his involvement in the Queen's diamond jubilee concert in June 2012 the "final straw", yet it seems she didn't contact police immediately but waited until late that year (
source)*. It's also unclear how a royal concert performance should be a final straw anyway in relation to sexual assault. Perhaps it was his success that annoyed her.
* Plus another source saying she didn't come forward until after the Savile allegations and apparently didn't make police her first port of call:
"In October 2012, Britain was rocked by a television documentary which revealed that Jimmy Savile, a beloved children’s entertainer who had recently died, was a prolific sexual abuser of children who gained access to his victims through decades of charitable work in schools, youth homes and hospitals. Police assigned to investigate were soon widening their inquiry to look at other entertainment figures and within weeks they had a tip from the NSPCC: a 47-year-old woman had told her counsellor she was sexually abused by Harris in her teens."

This business of adults reporting abuse to a children's charity or a journalist like MWT seems like inviting people to test run their story on a sympathetic ear before taking it to police.
