Dawn raids saw nine people arrested as part of a crackdown on drugs as police executed warrants at 12 addresses across Manchester, Trafford, Suffolk and West Midlands.
The raids were part of Operation Friction, a Serious and Organised Crime Group investigation which targeted an organised crime network supplying drugs across the UK.
The seven men and two women were arrested on suspicion of conspiracy to supply Class A and Class B drugs. They all remain in custody for questioning.
Five of the men and one of the women were arrested in the Greater Manchester area.Two of the men and one of the women were arrested in the West Midlands area.
Detective Inspector Tony Norman of GMP’s Serious and Organised Crime Group, said: “We now have nine people in custody as a result of the hard work of our dedicated officers together with the support of our colleagues from West Midlands Police and our partners.
“I want to thank our local communities as without them working with us and reporting these crimes, we couldn’t have carried out such an extensive operation and today’s raids show how committed we are to eradicating drugs from our streets.
“I would continue to urge people to report any suspicious activity to police so that we can stop criminals benefitting from organised crime and drug supply.”
