Four suspected triad members were among five people arrested during a raid on a Hong Kong flat by local customs officers who also seized an estimated HK$1.3 million in crack cocaine. The gang – four men and one woman – was suspected of using a Fung Yuen Road flat in Tai Po as a base to produce and distribute drugs. Plain-clothes officers intercepted the four men on the street just before 11pm and seized a kilogram of crack. The officers then stormed the flat, where they said they found 40 grams of cocaine, scales, chemicals and other tools.
