Police have discovered a large cannabis factory containing around 300 plants at a residential property in Swindon.

Officers made the discovery last week at a house on Laburnum Road, just off The Circle in Pinehurst, which was “full of an estimated 300 plants.”

The house has now been processed and a police investigation is underway.

Neighbours reported seeing police forensics teams at the scene for four consecutive days, although a police scene does not appear to still be in place at the property.

Swindon Advertiser:

No arrests have been made in connection with the factory.

Police have warned members of the public that cannabis factories are often “set up in a variety of places, including residential buildings which look innocuous from the outside.”

Signs that a factory is in operation at a property include the windows being permanently closed, high levels of condensation, a “sweet, sickly aroma”, lots of visitors, high electricity bills, constant ventilation noises and snow melting on the roof in winter.

A spokesperson for the force said: “If you suspect there is a cannabis factory next door, you should phone us on 101 or 999 if a crime is in progress.

“You can also report online to the Wiltshire Police Website or contact Crimestoppers on 0800 555111.”
