A Wigan home was among properties hit by dawn raids yesterday during a major crackdown on organised crime.
Warrants were executed at a total of 15 addresses as part of an ongoing investigation into crime groups centred in Salford, after detectives identified a criminal network involved in drugs supply and money laundering.
Seven people had last night been arrested on suspicion of conspiracy to supply class A drugs and in addition money laundering.
And a part of the investigation in excess of £200,000 value of class A drugs have been recovered and £30,000 in cash.
But details of individual addresses, including the ones in Wigan borough, Trafford, Manchester and Lancashire as well as Salford, have not been revealed.
Supt Mark Kenny of Salford division said: “We are continuing to disrupt and destroy organised crime groups in Salford and across Greater Manchester.
“We want to show our communities that we are listening to them and taking forceful action against those who are trying to ruin our communities.”
