Fake tickets are only the beginning, from Reuters:
Apart from run-of-the-mill confidence tricks from people selling pirated Olympic coins, gold bricks and other merchandise, police had heard reports of offers to arrange “Olympic securities and funds” through back-door connections, the Beijing News said, citing the Shanxi Public Security Bureau.
One imaginative scheme, in a list of nine of the most commonly reported stings, involved a scam to sell Olympic medals supposedly missing after a warehouse blaze, and in exchange the buyers could turn them into the government for “a high price.”
Another sought to extract fees from people who had been selected to receive “special training” to act as journalists during the sporting event, the paper said.
