A GANG set up a cannabis farm right under the noses of police.
Officers found a “significant number of plants” in an occupied office block’s basement yards from their district HQ.
Stairways had been bricked up to make it look like there was no lower level.
But when cops checked further they found hundreds of plants thought to have a street value of up to £9million.
The raid took place in Bradford on Monday but so many plants were found that the stench of cannabis could still be smelt on the street outside three days later.
A source said: “The smell was overpowering.
“Anyone walking past could smell it.
“There was no mistaking what it was.”
Six men aged between 22 and 63 were charged with the production of a Class B drug and have appeared before magistrates.
They are next due to appear at Bradford crown court in January.
West Yorkshire Police said: “Enquiries remain ongoing after officers uncovered the cannabis factory in the basement of a building on Nelson Street, Bradford, on November 25.”
