Prosecutor Chang Chun-hsiang directed police and criminal-investigation units to search a mountain site in Guoxing Township on 6 August 2018, where a man was living in an iron-sheet shelter and growing cannabis outside it for harvest and drying.[1] Officers seized 511 cannabis plants, 371.84 grams of seeds and 175.58 grams of dried leaves and buds, along with grinders, scales, timers, LED panels and other growing and packing tools.[1] They detained the adult man surnamed Deng who ran the site.[1]
The case had started in May, when a separate user case led investigators to Deng, who had already been sentenced to five years in prison for manufacturing cannabis and was wanted on a warrant.[1] Sixty officers took part in the 6 August search, and after questioning the prosecutor sought detention without visitation rights, which the Nantou District Court granted at about 11:30 that night.[1]
