According to a report in Bezirks Blätter, police found an illegal indoor cultivation of cannabis plants in a residential building in Innsbruck on Wednesday. This discovery led them to another 'grow-room' in the nearby town of Inzing.

The report states that a routine police patrol noticed a strong odour of marijuana plants while they were in a building on an unrelated matter.  

After obtaining entry to the suspect's apartment, police found 40 cannabis plants and a small amount of narcotics in the home of a 24-year-old man.

A similar 'grow-room' operation was recently found in Vienna.

An acquaintance of the owner, a 27-year-old Innsbruck man, was also found with 48 grammes of the cannabis herb.

In follow-up enquiries, police additionally found another indoor cultivation with a larger amount of narcotics in the apartment of a 26-year-old man in the nearby town of Inzing.

The three suspects have now been charged with various drug-related activities, including illicit cultivation.

Cultivation and personal use of cannabis remains a crime in Austria that is punishable by up to ten years in prison.
