Hong Kong customs officers have seized 6.5kg of suspected drugs worth about HK$3.4 million (US$433,800) and arrested two men in separate cases earlier this week.

The Customs and Excise Department said on Friday that the first arrest occurred two days earlier at Hong Kong International Airport, when officers found 3.1kg (6.8lbs) of suspected ketamine in the baggage of a 43-year-old man arriving from Bangkok.

The department said the suspected drug was concealed inside food packaging in the baggage.

In the second case, officers intercepted a man, aged 41, during an anti-narcotics operation in Yau Ma Tei on Thursday.

Officers escorted him to a nearby hotel room where, in a subsequent search, they found about 1.7kg of suspected cocaine and about 1.7kg of suspected “Ice”, or methamphetamine.

Officers also found “a drug inhaling apparatus and a batch of drug packaging paraphernalia”, according to the department.
