GETTYSNOW EVIDENCE: The house had an £80,000 cannabis farm in the attic
Two officers raided the property in Keighley, West Yorks, after spotting the clear tiles on a property close to Arctic Street.
The house was so warm, any snow that settled instantly melted.
However, all the neighbouring properties were covered in the white stuff.
Inside, officers discovered an elaborate heating set-up, ensuring more than 300 plants were being kept alive and toasty under highpowered lamps.
Pc James Butterfield, who conducted the raid, speculated the haul could be worth about £80,000 on the street.
Posting a snap of his work on Twitter, he said: “So this is what we got up to! My size 10 boots came in handy for entry.
“Removing this filth from the streets is always great. Knowing that the morons responsible for it are £80k out of pocket is a Brucey bonus! #didntwedowell.”
Colleague Pc Caroline Foster tweeted yesterday: “While the snow has kept the burglars at bay it has also helped us in finding some rather large plants.
“Hmmm, I wonder why there is no snow on your roof? 280+ plants seized from an address in Keighley today, some nearly 6ft tall.”
A police spokesman said: “The plants will now be officially examined and valued.”
Vicky Watson, 44, who lives next door, said two men in their 30s had recently moved into the house.
Vicky, left, added: “In the cold weather my house is normally freezing because the insulation is rubbish. But since they moved in my bathroom has been absolutely red hot. The wall was warm to touch.
“It was suspicious, you could hear fans whirring but no normal sounds of people living there.”
