HONG KONG (AFP) - Hong Kong police said Sunday they have made the southern Chinese territory's largest ever cocaine bust, seizing more than half a tonne of the drug, worth around $77 million. Authorities said drugs officers raided separate locations over the weekend, including a warehouse in the city's suburbs, finding a total of 567 kilograms of cocaine. Eight people were arrested, police said, ranging in age from 24 to 55. Those arrested included an American man, a Colombian woman with Hong Kong residency and five Mexicans, a police spokeswoman said.
