A traveller from Brazil was arrested at Hong Kong International Airport on Wednesday after her “exceptionally heavy” empty suitcase yielded 3.8kg of suspected cocaine with an estimated street value of HK$4.4 million. It was the third such seizure at the airport in seven days. The woman, 23, arrived in the city from Recife, Brazil, via Addis Ababa, Ethiopia. During customs clearance, officers emptied her check-in suitcase but found it was still a hefty bag, according to the Customs and Excise Department. “In-depth examination led to the discovery of three slabs of suspected cocaine concealed inside the false compartment of the suitcase,” the department said today. “It is believed the drug traffickers tried to use this concealment method to evade customs detection.” READ MORE: Australian police report shows crystal meth trail leading back to Hong Kong The traveller, who claimed to be a saleswoman, would appear in Tsuen Wan Court tomorrow on one count of trafficking in a dangerous drug, the department said.
