Although this is an isolated case (as far as I know), actions like this affect the reputations of all foreigners living in China.
Xin Kuai Bao (新快报), a newspaper based in Guangzhou, is reporting three drunk foreigners (according to the building's security guard) took a prostitute to their apartment in Yuexiu District around midnight Friday. A man in the building, Mr. Wang, reported hearing loud arguments coming from the suite on the 30th floor around 3am Saturday. Mr. Wang says she was shouting, "There are three people here, how can you pay just for one!"
Her body was found on an outdoor platform near the 11th and 12th floors later on Saturday morning, after she had allegedly been thrown from the 30th floor. Police cordoned off the area, and are now investigating.
