Police raided a converted office block on Glasgow Road in Paisley at about 11.30am on Tuesday 23 January 2018 and found more than 700 cannabis plants.[1] Officers put the crop’s estimated street value at £450,000 and arrested two women aged 53 and 55 and a 36-year-old man, who were released on an undertaking to attend court.[1] CCTV from a nearby Pizza Hut branch and the Lagoon Leisure Centre then linked four other men to the site, showing them entering and leaving.[2] The four had been watched by police in January 2018, and when officers entered, an immediate stench of cannabis led them to 718 plants growing across 13 rooms on three floors.[2] The setup was sophisticated, with fans, ducting, lighting, extra power sockets and reflective panels over the windows, and police believed it cost £50,000 to build.[2] In June 2019 the four admitted being concerned in the supply of cannabis.[2] On 3 September 2019 the High Court in Glasgow jailed Brian Scally, 37, and Ian Matthews, 37, for four years each and David Kerr, 30, and James Robertson, 39, for five years each, 18 years in total.[2] The court heard Scally treated the work like a job, Matthews acted as electrician, Kerr as joiner and Robertson, a landscape gardener, tended the plants.[2]
