Two Olympic silver medallists were left fearing for their lives after being mugged at knifepoint in Rio de Janeiro.
Sailing duo Hannah Mills and Saskia Clark, who came second in the women's 470 class at London 2012, were robbed as they walked back to their training base.
The former world champions have been in Brazil ahead of the Rio Olympics, due to take place in the summer of 2016.
Writing on their Facebook page, 470 Girls, they said:
Back in Rio for 2 weeks training. Top News Today: We've been mugged.
Our delightful walk back from the sailing club to the hotel turned fairly nasty when two guys wielding 7inch knives ran at us, pushed us around and grabbed everything we had.
Along with the things that were actually worth something, the most annoying thing right now is our lycra we were sailing in got taken. Unbelievable!!
Anyway, we made it back to the hotel slightly shaken but all okay.
American sprinter Tyson Gay has been suspended for one year after a positive drugs test, the US Anti-Doping Agency said.
Gay, 31, has had to return a silver medal won in the 4x100m relay at the 2012 Olympics in London.
The successful staging of the London 2012 Olympics has led to other countries turning to Britain to help deliver their own events, according to a government official.
Reacting to news that the UK had met its four-year target of raising £11 billion worth of economic benefit from the Games in 12 months, Trade and Investment Minister Lord Green said:
"The delivery of London 2012 on time and on budget led to hosting nations turning to the UK to help deliver their own events with supply opportunities running into the billions.
"UK Trade & Investment has played a key role in helping British companies maximise these opportunities and the result is a £11.06 billion boost to the UK economy from the Games, reaching our four-year target in just over a year."
A four-year target of raising £11 billion worth of economic benefit from the London Olympics has been met in 12 months, the Government has announced.
The country has benefited from new foreign investment, additional sales and firms winning contracts since last summer's events, according to a report.
The total includes £130 million of contracts won by UK companies for next year's soccer World Cup in Brazil, and the next Olympic Games, in Rio in 2016.
Boris Johnson reminded Tory conference delegates of his prediction that last year's London Olympics and Paralympics would spur a baby boom.
He told the Conservative Party conference: "I prophesied that the athletes had moved the people of this country to such paroxysms of excitement on the sofas of Britain that they had not only inspired a generation, but probably helped to create one as well."
"Like all my predictions and promises, I have delivered, in that GLA demographics say live births in London will be 136,942, which is more than in any year since 1966 when England won the World Cup."
Despite the beaming smiles of gold medal winners at London 2012, a study at last year's Games has found "high levels" of bad teeth among competing athletes.
Using data from 278 athletes from 25 sports, researchers found 55% had tooth decay or cavities, 45% had dental erosion and 76% had gingivitis. More than 40% were "bothered" by their oral health.
The study, published in the British Journal of Sports Medicine, concluded: "The oral health of athletes attending the dental clinic of the London 2012 Games was poor with a resulting substantial negative impact on well-being, training and performance."
Danny Boyle has said everyone who was part of the London 2012 opening ceremony was "honoured" to work with the "wonderful" stuntman Mark Sutton.
The event's creative director said Mr Sutton had formed "a brilliant partnership with Gary Connery" to make crowd inside "the (Olympic Stadium) gasp" and leave them with "indelible memories" in parachuting in as James Bond and the Queen.
Mr Boyle also paid joking tribute to Mr Sutton for helping to smuggle in treats for the Olympic team in the hard slog towards planning the global show, saying:
Courtesy of loading the helicopter in Essex, and thereby avoiding the official security ban on alcohol in the park during rehearsal, he and Gary also smuggled with them an excellent bottle of wine for the crew each evening and before we all went home we would often drink their health.
They of course, as top stuntmen, never touched a drop but they sensed our need of occasional fortification!
Friends and work colleagues have paid tribute to Olympic stuntman Mark Sutton.
Jackie Harper, a friend and fellow member of the Army Parachute Association at its skydive base in Netheravon in Wiltshire, said:
Mark was an expert wingsuit pilot, very highly regarded by everyone here at Netheravon. He was very generous with his time and giving help and advice to others.
We are devastated and send our condolences to his family and friends. We are really going to miss him.
RBS, where Mr Sutton worked as a contractor in the Markets division, offered "condolences to his family" and said everyone at the bank's "thoughts are with them at this very difficult time".
The family of Olympic stuntman Mark Sutton are understood to have flown to Switzerland following his death in a wingsuit flying accident.
His partner Victoria Homewood, though, is believed to already be there having reportedly travelled to Chamonix with him a few days ago.
The repatriation of Mr Sutton's body is expected to take a few days.
Olympic stuntman Mark Sutton's injuries from his fatal crash in the Swiss Alps have proven so severe that experts could only identify his body with a DNA test.
Mountain police said the daredevil wingsuit pilot was likely to have been flying at around 125mph (200kmh) when he hit the ridge. Investigators are examining if thermal winds played a part in his crash.
We do not know what caused his death but we know it was immediate. The weather was good but when a pilot takes part in this sport, the aim is to fly very close to the ground or mountain side. If you do this at speeds of 200kmh, the margin for error is very small.
Police said Mr Sutton is the first wingsuit pilot to die during a jump in the Valais region.
