A Chomutov investigator started prosecuting a 30-year-old man for unauthorised cultivation of plants containing a narcotic or psychotropic substance.[1] The man is known as a long-term marijuana user.[2] He faces a charge for unauthorised cultivation of plants containing a narcotic or psychotropic substance.[2] He was detained after an anonymous tip about unusual activity in his garden.[2] Detectives then investigated the tip, including carrying out a house search.[1]

At his home, in the garden of a family house in Chomutov, he had set up a fóliovník, a foil-covered polytunnel greenhouse, where he grew cannabis without permission instead of vegetables.[1] Police seized 17 cannabis plants during the search.[1] Some of the plants reached two metres tall.[2] The polytunnel was completely filled with the plants.[1] An expert examination of the seized plants found they contained a total of 48 grams of THC, tetrahydrocannabinol.[1]

Someone with no sympathy for his hobby reported the grower to police anonymously.[1] He had not managed to harvest the crop before police arrived, so uniformed officers harvested the mature plants.[1]
