To be more specific, there was a period when it snowed heavily and the snow cover formed and increased, yet not a single flake “stuck” on a particular area on the roof of the house, leading some to suspect foul play.

The police officers who responded to the scene confirmed the accuracy of their training when they found a thriving business—specifically, a cannabis culture—within. The heat used to cultivate the plants prevented snow from sticking to the roof, melting it almost instantly.

Police in the Netherlands are making mass arrests of people growing cannabis when melting snow reveals their secret.

Drug traffickers in the Netherlands are finding that the absence of snow on their roofs is a surprising obstacle.

The owner of the building faces many years in prison for growing cannabis in his own house. Although marijuana usage is tolerated on a personal level in the Netherlands, residents are restricted to growing no more than five plants in their homes.
