Two flight crew members have been arrested after customs officers seized about 18 kilos of suspected cocaine in an operation targeting drug trafficking through staff and passenger channels at Hong Kong International Airport.

A 39-year-old woman was arrested at a Tsim Sha Tsui hotel on Monday after just over 12 kilos of the drug was found in two black plastic bags the day before by airport customs.

A further six kilos was found in another black plastic bag on Tuesday, leading to the arrest of a 35-year-old man.

The suspected drugs, which Customs believe came from Africa, have a street value of about HK$23 million.

The pair will appear in West Kowloon Magistrates’ Court on Thursday. They have each been charged with one count of trafficking in a dangerous drug.
