1/1 POLICE have arrested a man after discovering a £1 million cannabis farm by using a thermal camera. The farm was found by officers in a property in Hall Royd, Shipley, yesterday, at around 4pm. There were roughly 500 cannabis plants in the building, spread across two floors and six rooms. It is estimated altogether they are worth more than £1 million in street value. A West Yorkshire Police spokesperson said a 33-year-old male, from Bradford, was arrested and remains in custody at this time. Officers are still examining the premises and dismantling the farm. Enquiries are ongoing. The cannabis farm was initially discovered after PCSO Verdeyen scanned the property with a thermal imaging camera.
