Team GB star Greg Rutherford has said a thief has put an "ultimate downer" on his Olympic Games by stealing his mobile phone.

Rutherford, who failed to defend his long jump gold medal last night, but took the bronze medal for Team GB, tweeted this evening saying his phone had been taken.

The Olympic hero and British record holder said he was particularly upset as the phone contained pictures and videos of his toddler son Milo.

"The ultimate downer from this champs is having my phone stolen. Just for the pics and videos of Milo," he tweeted.

It was the second disappointment for Rutherford, who last night said he was "gutted" to lose his Olympic title as he struggled to hold back tears.

In response to his tweet this evening, Belgian decathlete Thomas Van der Plaetsen said he had also had his mobile phone taken.

Jokingly telling Rutherford to "join the club", Van der Plaetsen tweeted saying his phone had been swiped "at the training track a few days ago."

The news comes just hours after American swimmer Ryan Lochte was reportedly held up at gunpoint.

Lochte was said to have been attending a party with Brazilian swimmer Thiago Pereira before he was robbed as he headed back in a taxi.
