Updated at 6.16pm: Customs officers have made the largest seizure of smuggled cigarettes in Hong Kong this year - estimated to be worth $11.25 million, a spokesman said on Monday. The two trans-shipment containers from Guangzhou, declaring a cargo of mosquito nets, were found to contain 7.5 million sticks of dutiable cigarettes at the Kwai Chung Container Terminal on Sunday. The duty potential was about $6 million, the spokesman said. A customs division commander, Rose Ho Ah-ying, said customs became suspicious when the containers carrying the items require many stopovers for their transshipments. Ms Ho said the smugglers had tried to use circuitous routings to avoid customs inspections. 'Initial investigations revealed that the consignment was destined for Guinea, West Africa via Spain. We believe that the smugglers were attempting to evade customs investigations by using circuitous routings to ship the cigarettes from one customs territory to another,' she said No arrests had been made on Monday, but investigations were continuing on Monday afternoon.
