Detective Inspector Roger Ashcroft, of Preston Police, said: “We welcome these convictions and sentences which will hopefully send a clear message to those who may be involved in organised crime that we will not sit back and tolerate this sort of activity in our city and on our streets.
“We will continue to work with our communities and partners build and work on our intelligence to constantly target those that may be involved in drugs supply, as well as the violence and anti-social behaviour that comes hand in hand with drug dealing so we can protect and keep safe the most vulnerable in our city.
“We want to disrupt and deal with those who may be involved in criminality, but also that we can warn and educate young people about the consequences of going down the same path. It’s also really important that as part of this work, communities feel stronger and more empowered to do what they can to prevent serious organised crime from becoming the community norm.”
