Hong Kong customs officials seized a total of 60 kilograms of cocaine from two air passengers at its international airport.
Police said 48 kg were found in suitcases carried by a 35-year-old Brazilian man arriving from Sao Paulo, and added up to the largest amount of narcotics ever found on an individual in the former British colony.
The other 12 kilograms were seized from the luggage of a 22-year-old Russian woman arriving on the same flight from Beijing, but authorities said they have no evidence to suggest the two passengers were working together.
The drugs seized had a total estimated street value of $7.5 million U.S. dollars, authorities said.
Police said customs officials became suspicious of the man because he was travelling alone with a large amount of luggage and suspicious of the woman because she looked nervous.
Hong Kong and Brazilian authorities are both conducting further investigations.
