Police Officers urge Renfrewshire public to be vigilant after series of cannabis cultivations found in properties

26th Mar 2026

Police Officers in Renfrewshire are urging the public to be vigilant to drug use in their area following a number of instances of cannabis cultivations being found within unoccupied properties.

Through proactive police work, officers have conducted search warrants at 20 properties since the beginning of the year. Many of these properties are rental accommodation and appear to be vacant.

In each address, cannabis plants have been found being grown at varying stages of maturity.

In addition to this, officers are increasingly finding that the electricity meter has been bypassed into the property in order to gain power illegally.

Officers have made 17 arrests and seized over 10,000 cannabis plants. The estimated street value of the seizures, for the most mature plants, is in excess of £5 million.

Detective Inspector Gordon Smith said: “This work has been ongoing in Paisley, Renfrew, Gourock and Greenock over the past three months and we are seeing an increasing number of properties being used which the public and neighbours may think are unoccupied.

“Those involved in drug supply may come to the address for a short period of time – perhaps even 20 or 30 minutes – at different times across the day.

“We are seeing sophisticated instances of the electricity meters being bypassed within these properties. This does not only present a fire risk to the property itself, but neighbours and adjacent properties, especially within common closes or flats.”

A Scottish Power Energy Networks spokesperson said: “Electricity theft and tampering with power supplies are extremely dangerous crimes that put lives at risk. Interfering with electrical equipment can cause fires, severe electric shock, and widespread power outages that impact entire communities.

“Our engineers regularly see the aftermath of dangerous, makeshift wiring, and it’s only through swift action from fire crews that more serious injuries are avoided. We work closely with police to identify and respond to incidents of tampering, and we urge anyone who suspects illegal activity to report it immediately.

“The consequences of electricity theft can be devastating — no one should risk their life, or the safety of others, for the sake of bypassing a meter.”

Group Commander Rod Anderson, Scottish Fire and Rescue Service, added: “One of the most common causes of fires in the home is overloaded circuits and malfunctioning appliances.

“With marijuana farms using substantial amounts of electricity, there is a real fire risk.

“These types of fires can spread rapidly, igniting nearby materials, which makes them difficult to extinguish quickly. When these burn, they can produce a variety of toxic fumes and gases.

“Bypassing electrical meters not only causes a significant risk to a property, but also to neighbours and nearby buildings.

“The Scottish Fire and Rescue Service will continue working alongside Police Scotland to identify and reduce any such fire risks.”

DI Smith continued: “We are committed to disrupting the supply of drugs. People may view this as not a harmful substance, however in production cases, this often masks other forms of serious and organised criminality.

“I’d urge anyone with concerns of drug crime in their area, or has information that can assist our enquiries, to report this to us so that we can investigate.”

Information can be passed to Police Scotland via 101 or anonymously on Crimestoppers on 0800 555 111.
