Drug officers from the Primorje-Gorski Kotar police, working with colleagues in Opatija and special units, searched homes, a house under construction and vehicles at several Liburnija sites on 14 May 2025 under warrants from the Rijeka county court.[1] They seized more than 140 cannabis plants between 27 centimetres and one metre tall and about 7,300 grams of marijuana, along with scales, fans, reflectors and cash in several currencies.[1] Police said the four Croatian men, aged 44, 49 and 60, had grown the plants this year to sell for profit.[1] After the investigation they were charged with unauthorised production and trafficking of drugs and handed to a pre-trial judge.[1]

Burin reported on 17 May that an investigating judge at the Rijeka county court had ordered all four men held in custody because they might reoffend if left at liberty.[2] Its account of the same case put the haul at 149 plants and about 7.3 kilograms of marijuana spread across grows in Mošćenička Draga, Veprinc and Rukavac.[2]
