Reacting to the sentence, PC Alastair Jarvis of Wiltshire Police said: “We know that our communities are concerned about drug dealing and the related criminality and anti-social behaviour that this kind of activity brings with it.
“This case allowed us to disrupt this supply chain and prevent a large quantity of drugs reaching our streets.
“We would urge anyone who has concern about drug dealing in their local area to call us and report it. You could be providing information and intelligence which helps us arrest offenders and bring them to justice.”
