HOHHOT -- Police have seized 400 kg of caffeine and arrested a suspect in North China's Inner Mongolia Autonomous Region.

The drug-control police of Inner Mongolia's Urad Middle Banner were tipped off in late August that Liu Sanhuan, a resident from the banner's Shihahe Township, was selling caffeine, which is listed as a highly controlled narcotic in China, a police spokesman said on Monday.

Police arrested Liu and seized 400 kg of caffeine on Sunday after an undercover investigation which lasted nearly a month, the spokesman said.

Liu confessed that he had bought 500 kg of caffeine between the end of July and early August from a drug trafficker in neighbouring Shanxi Province, and he had sold 100 kg before he was caught.
