Dutch cannabis growers are reportedly being caught by police - thanks to melting snow.

Officers have released a photo of a cannabis factory in the city of Haarlem that was found due to an unusual lack of snow. While the rooftops were covered with snow, this special roof was completely snow-free.

Growing cannabis needs temperatures far above those common in neighbouring residential buildings, so Dutch news reports say police look for cannabis farms by looking for roofs where snow appears to have melted.

Last week police broke into a house in the city of Zutphen, where they discovered a bedroom with 88 cannabis plants.

Police helicopters in the UK have used a similar heat-detection method for years. They said: "Our cameras can detect unusually high temperatures coming from buildings several thousand feet away – anyone growing cannabis, using rows of heat lamps will be found from the skies."
