Nottinghamshire Police are urging residents and landlords in Carlton, Nottinghamshire, to stay alert for signs of illegal cannabis farms following a recent investigation into a hidden growing operation. On February 23, 2026, officers released footage showing how criminals used a hole in a wall to connect two separate properties to hide their activities.
The warning follows the sentencing of Van Nguyen, 59, and Dung Nguyen, 52, at Nottingham Crown Court on February 19, 2026. Van Nguyen was jailed for eight months and Dung Nguyen received six months for their roles in running the drug operation.
During the investigation, police seized 220 cannabis plants with an estimated street value of £220,000 from properties on Newcastle Avenue in Worksop. Officers discovered the plants after finding a secret passage that had been knocked through the walls to link the two buildings together.
Local officials at Gedling Borough Council are working to protect the community through a licensing scheme that covers areas like Carlton Hill. This scheme allows the council to inspect private rental homes to find safety issues and reduce the risk of fires caused by tampered electricity lines.
Police say residents should look for clues such as pungent smells, windows that are always covered, or ventilation equipment that looks out of place. Landlords are also encouraged to check for high electricity bills or internal walls that have been changed without permission.
