A West Yorkshire Police report has found "no evidence" Jimmy Savile was protected from arrest or prosecution by his relationship with the force.
But the review found there was an "over-reliance on personal friendships" between Savile and some officers.
Hundreds of allegations of abuse by the former BBC entertainer emerged after his death in October 2011.
The police said the report would be passed to the Independent Police Complaints Commission.
The West Yorkshire Police review, named Operation Newgreen, comes after a report by Her Majesty's Inspectorate of Constabulary (HMIC) highlighted failings by forces across Britain.
