Alleged Taiwanese drug dealer, dubbed ‘Lupin Taiwan’, arrested in Bangkok for reportedly inventing and distributing deadly ‘K powdered milk’

Bangkok –

An alleged Taiwanese drug dealer, 38, was arrested in the Ratchathewi district of Bangkok yesterday, January 25th, for allegedly inventing the deadly ‘K powdered milk’ narcotic drug formula and distributing it nationally and internationally.

Deputy national police chief Suwat Chaengyodsuk revealed that national police had previously found K powdered milk hidden in a snack box in preparation for parcel delivery to the United Arab Emirates in October 2020. According to an examination, it contained a mixture of ketamine and crystal methamphetamine.

The parcel sender used a fake name and was discreetly relocating between luxury condominiums in Bangkok areas such as Lumpini, Rama 9, Town in Town, Ramkhamhaeng, and Sukhumvit. The investigation eventually led to the identification and the arrest of the suspect, Chou Yi Shen, at one of his condominiums.

Police discovered various kinds of narcotic drugs, including Ketamine and MDMA, and drug mixing equipment at his rooms. A recipe for making K powdered milk was also found noted in his phone.

According to the interrogation, Chou reportedly claimed that he was a drug mixer and dealer for foreign customers. He had ordered 280 grams of cocaine and 80 grams of cannabis from the United States to be shipped to Taiwan.

However, Taiwan authorities then issued an arrest warrant against him for drug possession and export, so he fled to Thailand in 2013 using a fake passport and continued his business here, using the dark web and bitcoin.

He nicknamed himself to be called among drug traders as ‘Lupin Taiwan’. He had reportedly changed his names and held many passports to deceive Thai law enforcement officers more than eight times.

The alleged drug dealer is now detained and under the supervision of the National Police. Meanwhile, the police are expanding their investigation as they believe that Chou did not act alone.
