Two men were arrested as police discovered a large cannabis factory in Daybrook.
Officers attended a derelict warehouse in Edwin Street at 12.20pm on Tuesday (27).
The unit adjourns a row of terraced houses and concerns were raised after cables were spotted bypassing an electric meter – posing a fire risk.
Officers gained entry to the warehouse and found approximately 600 plants spread over four large rooms.
Moments later, an officer spotted two men on the roof. They jumped down and ran but were quickly detained by officers.
The plants, with a street value of more than £500,000, have now been removed from the site and an array of sophisticated growing equipment has been put beyond use.
The two men, aged 20 and 27, were arrested on suspicion of the cultivation of cannabis and taken into custody.
PC Michael Callan, of Nottinghamshire Police, said: “This was a very large and sophisticated cannabis grow that had clearly taken some considerable time and expense to set up. I am pleased that we have disrupted the activities of whoever is operating it, and that we have taken a very significant quantity of drugs off the streets.
“We take the production and supply of illegal drugs extremely seriously and will not tolerate the cultivation of cannabis in our communities.
“In this case, the set up posed a very real fire risk to neighbouring properties, due to electricity being dangerously bypassed.
“We continue to urge the public to report local concerns around drug dealing to us, and to look out for the signs a property is being used to grow drugs.
“You can call 101 or speak anonymously via Crimestoppers on 0800 555 111.”
