Paul Costa, a 35-year-old go-kart worker, grew more than 100 cannabis plants in a concealed area of the Emotion Karting centre in Ayr between February 2013 and February 2015.[1][2] Police raided the site and found high-powered lamps and other growing equipment alongside the crop, which the court valued at up to £100,000.[1][2]

Costa denied responsibility at his trial at the High Court in Glasgow, claiming he had found the farm and was trying to catch the culprit when detectives raided the complex.[1] The court heard he had trawled the internet for growing tips, including a video titled “how to properly dry cannabis”, and police found his fingerprints in the growing area and his DNA on a juice can.[1][2]

Sentence

The jury rejected his account and convicted him of producing and supplying cannabis.[1] He was then sentenced at the High Court in Glasgow to four and a half years in prison.[2]
