Nuneaton officers have found a large cannabis grow near the town centre.
The police discovered a substantial heat source coming from the premise which appeared to be disused.
They then used police powers to force entry arresting two suspects for the cultivation of cannabis.
A police spokesperson said: "This resulted in hundreds of thousands of pounds worth of cannabis being taken off the streets and removing a significant safety concern for neighbouring properties."
