The Office of the Narcotics Control Board (ONCB) has expanded its investigation into the transnational drug trafficking network led by alleged kingpin "Sia Jiw", arresting two military officers accused of involvement in money laundering and drug transportation. Data retrieved from a confiscated mobile phone led investigators to identify the alleged mastermind as Chutthithan, known as "Sia Jiw", a former heroin convict arrested in 2006. On Feb 12, the ONCB and Provincial Police Region 5 raided eight locations across Chiang Mai, Chiang Rai, Nonthaburi and Bangkok. On Wednesday, authorities arrested a senior officer identified only as Lt Col Pan, attached to the permanent secretary's office, and his wife in Bangkok. Pol Lt Gen Suriya said that although Sia Jiw remains at large, the arrests have "cut off key financial and operational lifelines" of the network.
