The police have launched an investigation after a number of young cannabis plants were found in roundabouts and soft areas in Gozo.
The plants were discovered by workers of ELC - Environment Landscapes Consortium - who care for the areas.
The plants are being removed and destroyed.
A spokesman for ELC said he feared this could have been an attempt to undermine the company's reputation.
A company official in Gozo said the number of plants was substantial and it took workers all of yesterday and much of today to remove them. Policemen were present.
The plants were found in Xewkija, Ghajnsielem, Marsalforn and Victoria.
