A pair of ruby slippers worn by Judy Garland in The Wizard of Oz has been recovered by the FBI in a sting operation 13 years after being stolen

The shoes, often said to among the most valued props in movie history, were taken from a Minnesota museum in 2005, when someone broke in through a window late at night.

The FBI unveiled the slippers at a press conference on Tuesday, revealing that a "credible" tip last summer led to their return.

At the time of the theft, the pair was insured for $1 million (£775,000) but experts believe they could be worth at least twice that.

The FBI said a man approached the insurer in summer 2017 and said he could help get them back. After a nearly year-long investigation, the slippers were recovered in July during a sting operation in Minneapolis.

The slippers' authenticity was verified by comparing them with another pair at the Smithsonian's American history museum in Washington DC.
