Two drug trafficking cases will be brought up at West Kowloon Magistrates Courts on Monday, after 30 kilos of suspected ketamine - with a street value of HK$14 million - was seized at Hong Kong International Airport on Saturday.

The first case involves a man, aged 25 who had flown in from Frankfurt, and a 24-year woman who was arrested later at Hong Kong International Airport. The second involves a 47-year-old woman who had flown from Frankfurt, via Taipei.

Customs said all three suspects were locals.
