POLICE from Hong Kong and the Philippines are searching the territory for a man wanted in connection with the kidnapping of a Taiwanese businessman near Manila in May. Police want to question the man following the surrender last week of two senior Philippines police officers linked to a kidnap gang which used Hong Kong to secure its multi-million-dollar ransoms. Brigadier-General Dicatdor Alqueza and Colonel Reynaldo Berroya gave themselves up to the army after going into hiding last month. Arrest warrants for the two senior officers and 13 others were issued 10 days ago. They are all charged by the Philippine Presidential Anti-Crime Commission (PACC) with the kidnapping of Taiwanese businessman Jack Chou Chung-yih, who was abducted on May 11 while driving along an expressway outside Manila. Mr Chou was later released unharmed after his father travelled to Hong Kong and paid two kidnappers a 10 million peso (about HK$3 million) ransom. The PACC has linked the kidnapping syndicate to General Alqueza and Colonel Berroya, and believes it is also involved in smuggling large amounts of the drug ''ice'' into the country from Hong Kong. Police launched a full-scale search of the gang's suspected hideouts in Manila and neighbouring provinces last weekend, but no arrests were made. Following the surrender of General Alqueza and Colonel Berroya last week, two other policemen gave themselves up. The PACC has linked the police to a narcotics trafficking and kidnapping gang allegedly run by suspected drug-lord Manuel Tan, who was arrested in July and convicted of corruption offences dating back to 1980. Tan is believed to be the Philippines partner of a Hong Kong-based drug syndicate comprising a number of triads, including Wo Le Wo members and possibly a Sun Yee On gangster.
