A 52-year-old man was arrested at Hong Kong International Airport on Saturday for alleged drug trafficking.

The man arrived on Saturday afternoon from Rio de Janeiro in Brazil via Dubai in the United Arab Emirates, according to a government release.

He was arrested when customs officers found a slab of suspected cocaine, weighing about 1.7 kilograms with an estimated street value of HK$1.5 million (US$192,326) in a false compartment in his suitcase when he went through the check-in luggage examination.

If convicted, the man could be jailed for life and face a fine of up to $5 million.

Later, customs officers doing a follow-up investigation arrested a 24-year-old man, who holds a passport from a country in western Europe, in North Point on Hong Kong Island. Officers suspected he was also involved in the case.

The customs officers were investigating the source of the illegal drugs to see if a cross-border drug trafficking may be syndicate involved, Oriental Daily reported.
