Police arrest two men for selling yaba to students at a school in Chiang Rai Province on Tuesday, one of them using his own young son as part of the operation.
Arping Sae-Taew, 33, pretended to send his seven-year old son to the school to avoid drawing suspicion while he sold methamphetamine to students, according to a report in Kao Sod newspaper.
Police mounted a sting operation and found 16 yaba pills in Arping's pocket and four more pills with his associate, Tomanai Sae-Loo, 19.
The two said they get the pills from a friend in the area and sell to students at 100 baht each.
Police suggest parents and teachers closely monitor children's behaviour due to increasing drug distribution in school areas.
