NCRPO chief Deputy Director General Romeo Peña identified the suspects as Agripino Arevalo, 52, of Las Piñas City; Samson Tianchon, 49, of Sta. Mesa, Manila; Nelson Mallari, 49. of Muntinlupa City; Mario Jocsing Sr., of Multinational Village, Parañaque City; and Ernesto Arevalo, 56, an employee of the Department of Environment and Natural Resources and a resident of Patnongon, Antique.
The arrests were made by the NCRPO-Regional Intelligence and Special Operations Office headed by Senior Inspector Tom Tuzon during an entrapment operation Thursday at the SM South Mall in Las Piñas.
The operation was triggered by a complaint filed by an American businessman who claimed that the suspects, led by Arevalo, approached him last May and offered to sell him five bars of the precious metal palladium. Marvin Sy
