Customs officers seized $2 million worth of pirated discs yesterday in the largest such seizure this year. Officers raided a flat in Tai Nan Street, Shamshuipo, where they found about 70,000 pirated discs. The seizure included movies, computer games and software. Lo Kit-ming, divisional commander of the Customs Special Taskforce, said: 'We found the living room was littered with some 40,000 pirated discs. And later we discovered 20,000 more in rooms concealed behind [fake] walls.' Police believe the flat was being used as a warehouse for the discs. Two men and three women aged between 26 and 45, all mainlanders in Hong Kong on two-way permits, were arrested yesterday. Mr Lo said the five were paid between $100 and $150 per day to deliver the pirated discs to outlets across Mongkok. They had an elaborate scheme for delivering the discs, Mr Lo added. 'The mainlanders would not go directly from the storage centre to the outlets. The discs changed hands three times, among several two-way permit holders, before being dumped into the outlets,' he said. Police were making headway in finding the masterminds of the pirate disc syndicate, Mr Lo. In a separate operation, on Thursday, customs officers raided premises in Mongkok and found drugs and pirated discs. They found 660 grams of suspected cannabis worth about $50,000 in a flat in Kwong Wa Street, and also seized $230,000 worth of equipment. This included 12 disc copying machines, 78 CD writers, three computers and 6,000 pirated DVDs and VCDs. Two men and a woman, aged 20 to 26, were arrested.
