THE head of Guangdong police, Mr Chen Shaoji, disclosed yesterday that a three-day conference was currently underway in Guangzhou to discuss measures to stem the flood of illegal immigrants into Hongkong. He admitted that there was an increasing trend of snakeheads smuggling illegal immigrants into the territory. In the first four months of this year, Hongkong police had repatriated more than 14,000 illegal immigrants - 30 per cent up from the corresponding period last year. Senior Hongkong officials have said the flood is being seen as an increasing threat to law and order in the territory and have sought assistance from across the border to stop the flow. Mr Chen said options being considered included increased border patrols, deployment of more officers and the employment of more advanced transport and communications facilities. He hinted that Guangdong might be able to relocate officers previously battling smugglers using tai feis, or high-powered speedboats. But he made it clear that they would continue to work with Hongkong to ''eliminate about 20 tai feis'' still in operation. He said Guangdong's coastline offered natural hideouts to these speedboats, which has made the Government's anti-smuggling efforts more difficult. ''I must say that our co-operation with Hongkong police is getting better every day. I am very satisfied,'' the director said. While only 17 suspects were caught and repatriated to Hongkong last year, Mr Chen said 14 have been deported to the territory so far this year. The fight against smuggling of weapons into Hongkong had also made progress. By the end of April, Guangdong had confiscated 384 firearms (including 79 military-issued weapons), 1,288 rounds of ammunition and 15 grenades. Triads had also been kept under control, Mr Chen said. From January to March 2,683 criminal syndicates had been smashed and 10,306 suspects arrested.
