Two of Britain's Olympic heroes have had their medals stolen just 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 this morning at a Mayfair bar.
Police investigating the theft of the medals have arrested a 29-year-old man.
Ronke Phillips has our report.
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, under the username @hannahmacleod6, also wrote on the site: "My medal was also stolen at the same time. Totally devastated."
A host of Olympic and Paralympic stars had earlier been invited to the palace to mark their achievements along with the Queen, Duke of Edinburgh, Duchess of Cambridge, Prime Minister David Cameron and London 2012 chief Lord Coe.

We take matters like this extremely seriously, and are always concerned if any friend of Mahiki has a poor experience.
Incidents like this rarely ever happen at the club, and we pride ourselves on our safe, welcoming and fun environment; our calibre of clientele and our excellent security.
Which is why, when learning about the lost medals the police were contacted immediately.
We co-operated with the Met and invited them to review all.
They reviewed the relevant footage and told us that there is no evidence last night to suggest that Mr Partridge was robbed of his jacket or medal on the premises.
They have asked for further information of which we are passing on. We will continue to help Mr Partridge on his quest to find the medal and jacket and appeal for anyone who might know anything to help return these priceless possessions.
Anyone who finds the medal is of course guaranteed free treasure chest and Mahiki Coconut for life.
