A Thai woman spent 20 days in Japanese custody after unknowingly carrying a parcel with crystal methamphetamine hidden in coffee sachets. She was recruited via Line and paid to carry goods. Police say the network used Thai bank accounts and a delivery app. For a business owner: never carry or ship sealed packages for anyone else, and treat unusual job offers with translated-sounding messages as a red flag. Also watch that your own bank accounts are not rented out to others for transfers.
