Updated at 7.04pm: Cases involving smuggling increased in Hong Kong last year - with smuggled goods totalling $91.28 million being seized, the Marine Police said on Wednesday. In a review of the year 2000, the Marine Police said 283 smuggling cases were recorded and 836 people involved in smuggling were arrested. This compared with 129 cases, 420 arrests and seizures totalling $72.9 million in 1999. But the number of illegal immigrants arrested in Hong Kong fell, Marine Police regional commander Foo Tsun-kong said. He said arrests dropped to 8,476 in 2000 compared with 12,710 in 1999. There were 28 cases and 60 people arrested for aiding and abetting illegal immigrants compared with 34 cases involving 36 people in 1999. Mr Foo also said the Marine Region was commissioning a $70 million digital radio communication system to replace the existing ''very high frequency network''.
