This is the astonishing sight that greeted police officers investigating reports of "a few cannabis plants" in London.
The marijuana crop the size of a football pitch was found in the Grove Ward borough in Kingston upon Thames.
Photos of the crop were posted by officers, who tweeted: "Called to a few cannabis plants. We found a forest!"
The plants, some of which towered over the officers, were found in a residential area, a few streets from a university halls of residence and a sixth-form college.
