Members of the Philippine Drug Enforcement Agency (PDEA) and the Philippine National Police arrested two Taiwanese and four of their Filipino cohorts in Cagayan and seized from them about one kilo of suspected methamphetamine hydrochloride (shabu) and two kilos of a dangerous drug called ephedrine. Director Derrick Arnold Carreon of PDEA Regional Office 2 identified the Taiwanese as Ke Chyi Long, 36, and Tsay Jong Yih, 33. The four others arrested were Sanny Cangas, Mario Umengan and Alberto Dican, all from Calayan Island, and Dennis Albino of Ammunitan, Gonzaga, also in Cagayan. Their arrest came after a search of their reported hideout in Santa Ana, Cagayan, on December 16. The shabu was placed in a ziplock bag, while two other ziplock bags contained a mixture of shabu and ephedrine. Also recovered were 15 white sacks labeled as calcium chloride with white flakes suspected to be caustic soda weighing 40 kilograms. Caustic soda or sodium hydroxide is a white inorganic compound and widely used in the manufacture of shabu.
