BEIJING - Police in central China's Hubei Province have seized nearly 300 kg of ketamine and detained 12 suspects for making and selling the drugs in their latest crackdown.

The drug ring was operating out of a deserted poultry farm and deflected suspicion by claiming to be processing medicine, the public security bureau of Xishui County said Saturday.

The investigation that uncovered the ring took more than three months, the bureau said.

The case is still under investigation.
