China's top anti-drug official said the mass arrests had "sown terror" among drug criminals, according to a report Thursday in China's state-run newspaper Legal Daily. Liu Yuejin told the newspaper that he had called on China's police officers to use "unprecedented strength" and "extraordinary measures" in the operation. Legal Daily is controlled by China's Central Commission for Political and Legal Affairs. The raids were also reported by China's state-run news agency Xinhua.
