The seven were arrested in a series of co-ordinated dawn raids at addresses in Preston, Carnforth and Carlisle as part of #OpWarrior.
They were all arrested on suspicion of Conspiracy to Supply a Class A controlled drug and money laundering.
They are a 34-year-old man from Carnforth, a 35-year-old man from Carlisle, a 30-year-old man from Preston, a 33-year-old woman from Preston, a 43-year-old man from Preston, a 37-year-old man from Preston and a 29-year-old man from Preston.
They all remain in custody.
Operation Warrior is the name of Lancashire’s county-wide crime crackdown aimed at disrupting and tackling organised crime.
Warrior is dedicated to bringing more offenders to justice as well as stripping them of their cash, cars, and other assets.
In the last four months alone, Op Warrior has led to almost 300 arrests, close to 100 charges, more than 20 cash seizures and over 60 years imprisonment for offenders.
Det Chief Insp James Edmonds said: “I hope that our continued activity clearly shows how committed we are to tackling serious and organised crime which is a threat to communities across the country. It takes many forms including drug trafficking, human trafficking, illegal immigration, fraud and financial crime, counterfeiting, organised acquisitive crime, cybercrime, and exploitation.”
Andrew Snowden, Lancashire’s Police and Crime Commissioner added: “It’s important that we send a clear message to criminals that police are coming to get you, and this is another great example of the work officers do, every single day, to disrupt and dismantle organised crime gangs and put them behind bars.
“It’s what Op Warrior is all about taking the fight to criminals that blight our communities, delivering on my Fighting Crime Plan and seeing even more arrests, more asset seizures and more drugs off our streets.”
Lancashire Police are still appealing for anyone with information about organised crime to contact them or independent charity Crimestoppers anonymously. Information leading to an arrest could lead to a reward of up to £1,000.
