Police in the settlement of Leningradsky near Kemerovo found a large cannabis plantation inside the building of a former boarding school.[1] Those behind the operation had bought the former boarding-school building specifically to use it for illegal cultivation.[1] The organisers were described as residents of Krasnoyarsk Krai and of a Central Asian country, and they were detained and placed in a pre-trial detention centre to await trial.[1] The detention report states that they were held in custody pending trial.[1]

Inside the building, the growers had fitted out greenhouses with modern heating, irrigation and ventilation systems.[1] During the subsequent search, officers found more than 1,800 cannabis plants growing in the school building.[1] Officers also seized 32 kilograms of ready-to-use marijuana during the same search.[1]

Police said they seized the large batch of cannabis cultivated in the abandoned school, and a criminal case on drug production was opened over the operation.[1] The account identifies the seized crop as cannabis grown in the abandoned school.[1]
