In the week before 26 May 2026, Aargau police searched several halls on a commercial site in Wallbach and found two indoor cannabis plantations.[1] They seized about 2,500 plants and 130 kg of marijuana.[1] Adrian Schuler, spokesman for the senior prosecutor’s office of Aargau, said the two grows had room for 6,800 plants in all.[1]

The site also holds workshops and a padel court.[1] Two men had rented the halls that were searched.[1] The paper said it appeared that legal CBD hemp had been grown there at first, and that the operators may later have changed the business.[1] A ventilation system pointed to a professional setup.[1]

Schuler told Tele M1 that eight people were arrested and that four were in pre-trial detention.[1] The prosecutor’s office gave no ages or nationalities.[1] The investigation is for commercial drug trafficking.[1] Tele M1 reported the same raid, with 2,500 cannabis plants and eight arrests, and said officers had been at the commercial quarter for several days.[2]
