Police have carried out drugs raids in King’s Lynn and Dereham as part of Operation Mile.
Across Norfolk, officers seized more than £900,000 worth of cannabis and 1,600 cannabis plants worth a total of £800,000.
Chief Superintendent Dave Buckley said: “As well as making 22 arrests so far and seizing plants and cannabis we were successful in further disrupting activity connected to Serious and Organised Crime in Norfolk.
“It’s important to remember the impact of this kind of crime can have within communities and the serious violence and acquisitive crime associated. The proceeds from these grows can often be used to fund other criminal enterprises. We will continue to work with local communities to disrupt this crime and ensure Norfolk is a hostile environment for criminal groups.”
Anyone with information about a potential cannabis factory or drug dealing can contact Norfolk Police on 101 or 999 in an emergency.
People can also contact Crimestoppers, anonymously, on 0800 555 111 or crimestoppers-uk.org
There are some key signs to spot a property could be being used as a cannabis factory:
Frequent visitors to a property at unsocial hours throughout the day and night.
Blacked out windows or condensation on the windows, even when it is not cold outside.
Bright lights in rooms throughout the night.
Electricity meters being tampered with/altered and new cabling, sometimes leading to street lighting. High electricity bills could also be an indicator.
A powerful, distinctive, sweet, sickly aroma and noise from fans.
Lots of work or deliveries of equipment to an address, particularly those associated with growing plants indoors without soil such as heaters and lighting. An excessive amount of plant pots, chemicals, fertilisers, and compost.
