Han, 35, allegedly paid tourists to bring in the drugs to Incheon International Airport from where he transported it inside fruit boxes as express bus cargo to Kim, 41, on three occasions.

Kim then carried the boxes to public bathrooms and taped the sacs to toilet covers for clients to collect.

Kim told the police no one suspected him as he carried fruit boxes.

Kim’s cover was blown after a woman Kim met through an online chatting platform discovered it and reported the white powder in his fruit boxes.

The police said they confiscated 30 grams of meth, worth 100 million won ($84,500).

Among the people who purchased the drugs, three were arrested and 31 others were booked without detention.

The police plan to rake out the Cambodia-based trafficking organizations -- Tomato and Cheongpoongmyeongwol.
