Chinese nationals have been warned to tighten their security here after reportedly being involved in several incidents following their arrival this week, including one bizarre robbery involving athlete Shi Dongpeng.
Shi, one of the country's leading athletes who won a silver medal in the 110 metres hurdles at the Doha 2006 Asian Games, had just checked into his hotel on arrival with an accompanying cameraman when approached by a local who appeared drunk.
According to the International Sport Press Association (AIPS), the man then vomited over Shi, who went to clean himself up while the cameraman chased the man out of the hotel.
When they returned, all of the camermans equipment had been stolen, as well as baggage belonging to both men.
Surveillance footage showed that they had been the victims of a cleverly organised professional job in which they had been distracted by the apparent drunk.
When the two tried to report the theft to Rio police, they found a two-hour wait due a long line of other people reporting having been mugged.
