Snowboarder Jenny Jones has asked for the public's help after her laptop was stolen from her car with all her Winter Olympic photographs on it.
Ms Jones - originally from Downend near Bristol - who won the bronze medal at Sochi said she was "devastated" to have lost two year's worth of photographs.
Writing on Facebook, she said: "Last night I had my laptop stolen from my car in Hammersmith."
She also posted on Twitter asking people: "Please keep ear to ground."
Jones, 34, discovered her love of snowboarding aged 17 after having a free half hour lesson on a dry ski slope with her brothers in Somerset, and she later decided to pursue the sport full time.
She won a medal in the women's snowboard slopestyle final, the first time Great Britain has won a medal on snow.
"It has ALL my Olympic photos on it and from the past two years," she wrote on Facebook.
"I am devastated to have lost such amazing memories.
"I would be so grateful if your in this area of London if you can keep your hear to the ground, I know its a long shot but got to try everything. Thanks jenny x."
