Ninety-three people, including 50 foreigners, have been held under administrative detention for using drugs at an overpass culvert in Shenzhen's Nanshan district early Sunday, according to sources with the Nanshan public security bureau of the city in South China's Guangdong province.

Two other foreigners have been detained on criminal charges on suspicion of drug trafficking, the bureau said in a post on the micro-blogging site Sina Weibo.
