During the raids, which were carried out under Operation Vicenza, police also seized suspected class A drugs and a number of assets including signed football memorabilia and cash. Chief Superintendent Emily Higham, of GMP’s Wigan district, said: "This morning’s action is a prime example of the work we need to be doing to fight, prevent and reduce crime.
"We understand the impact drug dealing has and simply won’t tolerate it, especially when it so often makes people feel unsafe within the communities in which they live. I’d like to use this opportunity to ask members of the public to keep talking to us – the intelligence you provide is key in these types of investigations."
