More than 800 plants have been seized after a tip-off about a “strong smell of cannabis” led to a raid on a building close to the Bank of England.
City of London Police said it was the first find of its kind in the financial district – currently largely deserted because of the COVID-19 crisis.
A statement said: “This is the first cannabis factory in the City, no doubt being set up in response to fewer people being out and about during the pandemic who might have noticed any unusual activity.”
A total of 826 cannabis plants were found and destroyed a week ago, it added, though there was no information on exactly where the raid took place.
Two suspects were arrested.
News of the police operation drew attention from Bank of England governor, Andrew Bailey.
He told an online event hosted by the Bank on Wednesday: “We are now going to be the subject of endless jokes about now we know what the Bank of England has been on.
“I’m sure there will be many other jokes. It is very quiet around the Bank of England, I should say.”
