Cannabis plants with an estimated street value of a quarter of a million pounds were seized by police following a raid in West Norfolk on Sunday.
The discovery of 3,500 plants at a property in Walsoken is one of the largest of its kind in the west of the county and followed a tip off by local patrol officers who noticed a strange smell in the air.
Police from Downham Market Safer Neighbourhood Team raided the address on Sparrowgate Road and discovered a large number of cannabis plants, generators and drug growing equipment.
The cannabis farm was discovered in outbuildings around the property with evidence also being seized from the house.
No arrests have been made at this time but enquiries are ongoing.
King’s Lynn and West Norfolk Superintendent Carl Edwards, said: “This is a major drugs seizure for West Norfolk and a successful result that demonstrates that illegal drug activity will not be tolerated in the community.
“Although no arrests have been made to date we are pursuing a number of lines of enquiry and will bring these people to justice.”
Officers attended the address after local officers identified a strong smell of cannabis in the air during regular patrols in the area, eventually leading to the property being identified.
Downham Sgt Andy Crown, who led Sunday’s operation, said: “The quantity of drugs seized reflects the strength of the very distinctive smell noticed by officers on patrol in the area.
“Inside the address we found a sophisticated cannabis production set-up clearly destined for the streets.
“We urge anyone with information about drug activity within their community to contact police on 101 - people can be reassured we will act on information passed to us.”
The Crimestoppers charity’s campaign to raise awareness of the issue asks people to keep an eye – and a nose out – for signs of cannabis production in their neighbourhood.
These include a strong sickly sweet smell in the air, constantly covered or blocked off windows at a property, visitors at unsociable hours, strong and constant lighting day and night, high levels of heat and condensation, a constant buzz of ventilation and lots of cables.
Anyone with further information about this incident or with information about drugs activity in their neighbourhood is asked to contact Norfolk police on 101 or alternatively call Crimestoppers anonymously on 0800-555111.
