Six suspects, including the ring's mastermind surnamed Ting, were arrested in what may be the largest arms smuggling bust ever in Taiwan, the Criminal Investigation Bureau (CIB) said Saturday. CIB officials displayed their haul of 181 guns and 22,685 rounds of ammunition in the lobby of its crime-fighting center in southern Taiwan's Kaohsiung City. Powerful submachine guns, rifles, and expanding 'dum dum' bullets were shown in the center, which took on the look of an arms depot. National Police Agency Director-General Wang Cho-chiun was on hand to laud the efforts of the police, expressing his appreciation for the assistance of Kaohsiung prosecutors and the cooperation among police in several cities sand counties. Police were tipped off several months ago that Ting was attempting to use a fishing vessel, the Kaohsiung-registered Hung Hsin, to smuggle a large haul of arms into Taiwan from the Philippines. The center and the Kaohsiung Harbor then formed a task force on the matter, and when the ship sailed into Cijin, Kaohsiung, police raided the vessel and seized the arms hidden on board. Two Taiwanese men who were guarding the stash and several Chinese fishermen on the ship were also taken into custody. Ting was later arrested in Pingtung County's Likang township. CIB officials said the seized weapons are standard models manufactured in Italy, Germany, Israel and the United States, with some used by professional killers and secret servicemen. Police had to spend the night counting and recording the large haul of arms, and one officer said he had never seen so many smuggled arms, which made 'it look like they were supplied for free.' But police also said breathed a sigh of relief after the arrest of Ting, who has a lengthy criminal record. Ting previously collaborated with Philippine rebels to kidnap a Taiwanese businessman surnamed Liu in 2006 when the latter traveled to Manila for business. Ting asked for a ransom of N$240 million (US$7.27 million) from Liu's family, but Liu later escaped. Ting has also been identified as the arms supplier of several notorious gunmen, including Huang Hung Yu and Lin Lai-fu, in Taiwan.
