NANNING -- Police in south China's Guangxi Zhuang autonomous region have confiscated 659 kilograms of ketamine in a recent crackdown on drugs.

Police with the public security bureau of Hechi City also arrested eight drug dealers, while confiscating a vehicle and 200,000 yuan ($29,039) from drug transactions.

In September, police received a tip-off about several non-locals making drugs in a remote mountain village in Hechi. Two months of investigation showed that a couple provided drug manufacturing sites, while other suspects supplied money and drug-producing techniques. The final products were then sold in Hechi and neighboring areas.

Further investigation is under way.
