Police arrested four suspected traffickers of illicit drug cocktail known locally as “K-powdered milk” in Bangkok on Tuesday.
Two of the suspects were believed to be small traffickers — Wirat Kaphueak, 26, of Sathon district, and Watchara Chiangchin, 22, of Thung Khru district.
The others were suspected middle-level traffickers — Chatree Srisombat, 18, of Yannawa district and Nopakao Obthom, 26, of Buri Ram’s Krasang district.
They were arrested in Bangkok on Tuesday after seven people reportedly died of overdosing on the drug cocktail in the capital. Six died on Sunday in an area under the jurisdiction of Wat Phraya Krai police station and the other died on Tuesday in the area under the Sutthisan police station.
A man, 23, and a woman, 24, both of whom knew one of the dead victims, remained unconscious, allegedly after taking the newly discovered illicit drug cocktail.
The four suspects were charged with possessing and trafficking methamphetamine, heroine and ketamine.
After questioning them at Wat Phraya Krai station, national police chief Pol Gen Suwat Jangyodsuk said more suspects would be arrested as police were looking for the source of the illicit drug cocktail.
He also said that ketamine was found in the bodies of all dead victims.
Earlier reports said that the “K-powdered milk” cocktail consisted of methamphetamine, heroine, ketamine and substances from sleeping pills.
