Police in Hong Kong say they have seized 560 kilograms of cocaine and arrested eight people in the territory's largest-ever cocaine bust. The chief of the police narcotics bureau said some of the drugs could have been destined for other countries. He said five men and three women were arrested in a series of raids that began Friday and they included five Mexicans, an American and a Colombian. According to Narcotics officers, cocaine estimated to cost 77 million dollars was seized from a large warehouse and several other locations around the city.
