The arrest of Sayan Huaithong was made possible by arrests of small-scale dealers who tipped police off that the suspect would be making a delivery in Phra Khanong using his Toyota Wish car. Police stopped the suspect and searched his car, uncovering the ya ba. The rest of the drugs were found at his home in Soi Suan Plu 8. The suspect, charged with possessing narcotics with intent to sell, reportedly confessed to delivering drugs on three earlier occasions. He had expected to be paid Bt200,000 for the delivery he was making when stopped by police. He said he got the drugs from a major dealer identified as Chai. Police were investigating.
