On 22 March 2026 the Diekirch public prosecutor’s office said the Grand Ducal Police opened an inquiry after the owner of a rented single-family house reported a foreign tenant.[1][2][3][4][5][6][7] Officers searched the property in northern Luxembourg, near the Belgian border, and seized 1,746 cannabis plants grown indoors along with large quantities of cultivation material.[1][2][3][4][5][8][6]

Two suspects who were in Luxembourg illegally and lived in the house to tend the plants were arrested.[1][2][3][4][5][8][6][7] They appeared before an examining magistrate in Diekirch on 23 March and were charged under Luxembourg’s 1973 drug law with cultivating cannabis, putting the drugs into circulation and laundering the proceeds.[1][2][3][4][8][6] The magistrate issued arrest warrants and both men were held in pretrial detention.[1][2][4][5][8][6]

The prosecutor said early work by the judicial police narcotics section indicated they had acted as an association; the investigation was continuing.[1][2][3][6] The statement was made public on 14 April 2026.[1][2]
