A man has been arrested by police investigating the alleged theft of two Olympic bronze medals from a Mayfair nightclub.
Medals belonging to rower Alex Partridge and hockey team member Hannah Macleod were apparently stolen hours after attending a Buckingham Palace celebration of their success.
Both athletes - who competed at this year's Olympic Games - had left their jackets unattended whilst at the Mahiki nightclub. They later realised the jackets, and the medals inside them, were gone.
A 31-year-old man has been arrested in connection with the investigation, and is being held at a west London police station.
Earlier, Macleod wrote on Twitter that she was "totally devastated" by the loss of her medal.
She added: "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."
Detective Chief Inspector James Harman said: "I would appeal to anyone who was in the venue in the early hours of Wednesday and saw anything suspicious to contact us - any information, no matter how insignificant it may seem, could prove vital to this investigation.
"My team have spoken to both Olympians who are understandably desperate to be reunited with the medals they have dedicated their careers to win.
"If you know who is responsible or where the medals are, please call us."
Scores 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.
