LONDON: Two Olympians have had their medals stolen during a night out after leaving a Buckingham Palace reception with Queen Elizabeth II to honour British athletes who took part in this summer's Games.

Rower Alex Partridge and hockey player Hannah Macleod took to Twitter to publicise the search for their missing Olympic bronze medals, which disappeared while they were at a club in Mayfair, central London, in the early hours of Wednesday.

Partridge, 31, said both his Olympic blazer and medal were stolen and asked for the items to be returned.

He and Team GB also tweeted a photograph of a man whom they believe may have information about what happened.

Scotland Yard said it was looking into reports of a stolen Olympic medal and blazer from a venue in Mayfair.

“It was believed the items were taken between midnight and 5am on Wednesday, October 24,” the spokesman said, adding that no arrests have been made.

Macleod, 28, also said on Twitter that she was “devastated” after her medal was taken at the same time but Scotland Yard said it had not yet been informed about the second missing medal.

“I'm not after punishment. If you picked up a Bronze Olympic medal that isn't yours pls just send anonymously back to GB hockey-Bisham Abbey,” Macleod wrote.

Partridge and Macleod were among British Olympic and Paralympic stars who attended a Buckingham Palace reception on Tuesday at which Prime Minister David Cameron and London 2012 chief Sebastian Coe were also present.
