An IPCC investigation into North Yorkshire Police has decided there is no case of misconduct to answer. Apparently the Officer did a great job of investigating Savile. He just didn't bother submitting a report, which may have helped future investigations.
// A detective failed to submit an intelligence report about Jimmy Savile and an ex-mayor after allegations were made against them, a report has found.
It stated the officer "should have submitted an intelligence report about Savile in 2002, based on his enquiries, which may have helped future investigations".
"While there are learning points to take from the report, it is also balanced by acknowledging the officer's tenacity and competence in dealing with serious matters."
The IPCC investigation concluded the detective sergeant, a constable based at Scarborough/Filey CID at the time, investigated "diligently and professionally" in relation to both cases. //

Seems a bit odd?
