Two of Britain\'s Olympic champions have reportedly had their medals stolen, only hours after the Queen hosted a glittering Buckingham Palace event to celebrate London 2012 athletes. Rower Alex Partridge and hockey star Hannah Macleod took to social networking site Twitter to appeal for information to find their Olympic bronze medals which they believe were taken in the early hours of Wednesday morning. Partridge, 31, who won bronze as part of the men\'s eight rowing team, tweeted that his Olympic blazer as well as his medal had been stolen from an event in Mayfair, central London. Macleod also wrote on the site: \"My medal was also stolen at the same time. Totally devastated.\" She added: I\'m not after punishment. If you picked up a Bronze Olympic medal that isn\'t yours pls just send it anonymously back to GB hockey-Bisham Abbey.\" Both athletes later published a photo of a man captured on CCTV who they wished to talk to about the alleged thefts. Scotland Yard confirmed it was investigating reports of a stolen Olympic medal and blazer from an event in Mayfair. However the force had not yet been contacted about a second stolen medal, a Metropolitan police spokesman said. A host of Olympic and Paralympic stars were invited to the palace on Tuesday to mark their achievements along with the Queen, Duke of Edinburgh, Duchess of Cambridge, Prime Minister David Cameron and London 2012 chief Lord Coe.
