Hundreds of cannabis plants worth more than £400,000 have been seized in Dewsbury after police dismantled a drugs factory in the town.

Police are continuing to investigate after seizing 470 cannabis plants in an operation in former shop premises in Dewsbury town centre last week.

Officers forced entry to the former commercial premises on Monday, April 17 and found four large rooms filled with plants spread across the building.

West Yorkshire Fire and Rescue Service attended to help police access the building which was in a state of disrepair.

Due to the unsafe nature of parts of the premises, the removal of the cannabis took place over the next few days.

Scenes of crime forensic work were carried out in the building and the seized plants have now been sent for destruction.

Sergeant Shaun Oates of the Dewsbury and Mirfield NPT, said: “A significant amount of work has been ongoing in Dewsbury so far in 2023 to disrupt drug offending, with this latest very large seizure being one of several recent operations.

“Money generated through the production and sale of cannabis goes directly into the pockets of organised criminals and is used to fuel crimes such as county lines trafficking which blights lives and communities.

“We are continuing to investigate this large seizure and I would ask anyone who can assist our enquiries or who saw suspicious activity in these buildings to contact the Dewsbury and Mirfield NPT.”

He added: “I want to thank everyone who comes forward and provides information about drugs crime in the Dewsbury and Mirfield areas. All reports are fully investigated and can lead to operations such as last week’s.”

Anyone who can assist police enquiries regarding the cannabis farm at Daisy Hill is asked to contact the Dewsbury and Mirfield NPT on 101 referencing police crime number 13230211625.
