Operation Yewtree is a police investigation into alleged sexual abuse, predominantly the abuse of children, by the British media personality Jimmy Savile (who died in 2011) and others. The investigation led by the Metropolitan Police Service started in October 2012. After a period of assessment it became a full criminal investigation, involving inquiries into living people as well as Savile.
On 19 October 2012 the Metropolitan Police reported that more than 400 lines of enquiry had been assessed and over 200 potential victims had been identified. By 11 December, seven people had been questioned, and the number of alleged victims was estimated at over 500. It was anticipated that the report of the investigations would be published early in 2013.
