About 200 cannabis plants have been found in a disused shop in Pelsall.
Police were called to the store on Mouse Hill just after 5pm Saturday by a member of the public reporting suspicious activity.
Officers attended and discovered over 200 plants under specialist heat lamps spread over three floors. No offenders were at the scene.
Electricians were called to make the building safe before officers were drafted in to destroy the plants and the hydroponic growing system.
Forensic scene investigators attended and enquiries are continuing.
Detective Constable Eliot Burns, from Force CID, said: “Some people may be under the illusion that cannabis is a harmless drug. The reality is quite different. We know that cannabis farms cultivate more than drugs – they are often managed by organised gangs who are heavily involved in gun crime, money laundering, human trafficking and serious violence.
“The electricity supply fuelling the heaters, which create a tropical environment for the plant,s is almost always illegally connected to the mains supply by unqualified electricians putting neighbouring properties at serious risk of fire.
“I would strongly urge people with suspicions about cannabis farms in their area to call us.”
Anyone with information which may aid the police investigation should call police on 101. People who do not want to speak with police officers can leave information anonymously on 0800 555 111.
Police said that signs that a cannabis farm may be in a property include:
- Gardening equipment such as plant pots, fertiliser and compost being taken into a property − particularly if the property doesn’t have a garden.
- Frequent visitors to the property, often at unusual times.
- Windows sealed or covers or curtains permanently drawn may be an attempt to hide what’s happening behind closed doors.
- Heat from adjoining properties could indicate that an artificial climate is being created for the tropical plants.
- Pungent smells from the cannabis plants and strange sounds from heating equipment extractor fans.
