POLICE have discovered a cannabis factory hidden behind a false wall in South Norwood.
Officers used an angle grinder to access the stash which in a disused car repair garage in Oliver Grove at 7am on Wednesday.
The plants were behind a false wall in a locker room which was concealed by two lockers bolted to a hidden door.
The factory was fully-functioning and contained around 70 plants which were ready to be harvested.
No one was present at the scene but the police involved in the investigation are attempting to trace the owners of the property.
It is the second cannabis farm discovered by Selhurst Policing Team this week. News of the find was later tweeted by Sergeant Kenny Parker.
The energy supplier confirmed to the police that the factory was being powered by an illegal connection, which has now been made safe.
Sgt Parker said: "Selhurst Policing Team will take action when people suspect the presence of drugs in their community.
"It appears that in this case the electricity supply had been diverted and was being sourced through an illegal connection.
"Combined with the heat and equipment there is a real risk of fire causing harm to people, buildings and property.
"We urge our community to contact us if they suspect this activity is taking place and we will treat their information with confidence."
