SMUGGLERS are using sophisticated lookouts around the territory to monitor the movements of Marine Police and the anti-smuggling taskforce, sparking a police intelligence crackdown. Police believe car smugglers now have spies on Cheung Chau hilltops, Shau Kei Wan rooftops and Sai Kung peaks equipped with radio scanners, mobile phones and infra-red night vision equipment. In Sai Kung alone - the last refuge for high-speed smuggling boats - intelligence reports have revealed three sites near the High Island reservoir, Wong Shek pier and the hills above the Wong Chuk Wan village. Police are planning raids on the lookouts but fear that unless the spies can be linked to a specific case, prosecution could prove difficult. Superintendent Ma Siu-yip, taskforce staff officer (operations) said: ''From what we understand, those acting as lookouts are using the sort of equipment commonly available all around Hong Kong, such as infra-red telescopes and binoculars. ''From an evidential aspect we have to make an arrest in relation to a specific smuggling transaction otherwise there's not much you can do about someone standing on a hill.'' The lookouts have appeared recently following a string of taskforce successes against the outlawed high-speed tai fei and chung fei smuggling boats which used to run nightly trips loaded with cars into Deep Bay and Mirs Bay. The introduction of the taskforce, doubled in strength in April, has forced car smugglers to start using cargo barges loaded with secondhand cars leaving Hong Kong. Fast boat sightings have dropped from about 2,000 two years ago to just 150 or so each month, with the gnarled, dark coastline of Sai Kung remaining a favourite haunt. Up to August this year, the taskforce arrested 184 people for smuggling and related offences and seized $31 million worth of goods - mainly cars and electrical goods. The sites on Cheung Chau, meanwhile, are used mainly to support barge operations. The cargos on the barges often have legitimate Customs Department export licences for countries such as Vietnam or the Philippines. The barges are towed just out of Hong Kong waters, where cars are transferred to smuggling boats. Meanwhile, Regional Services Department (RSD) staff are on the alert after the first interception at sea of a load of uninspected pork from China. The 1,650-kilogram haul on board two sampans off Starling Inlet near Sha Tau Kok this week has yielded reports of other shipments to Lau Fau Shan and Luk Keng. A 33-year-old man has since been fined the maximum of $5,000 and the pork has been destroyed. Yip Hoi-wing, RSD Chief Health Inspector of North District, said he was liaising with police and Department of Health officials to ''nip this . . . trend in the bud''. ''I cannot emphasise too strongly that it is very dangerous to consume uninspected pork which poses grave potential danger to one's health. ''I appeal to all . . . consumers to be on the alert when offered unusually cheap pork.''
