Twelve people have been arrested in early morning raids in Greater Manchester targeting suspected drug dealers.
Twelve people were arrested during the raids
Class A drugs were also seized during the raids involving 100 officers in Stretford and Old Trafford.
The men and women were being questioned on suspicion of supplying crack cocaine and heroin.
Trafford Borough Council said it would investigate any council tenants who were found to be in breach of their tenancy agreements as a result of the raids.
Officers have also identified four other people they want to speak to in connection with drugs offences and have released pictures in the hope people will recognise them.
Police want to interview these men about drugs offences
Officers raided 14 addresses simultaneously at 0600 GMT following three months of intelligence gathering.
Chief Inspector Gill Mellor, of Greater Manchester Police, said:
"Operation Reuss was launched as a result of information we received from the local community.
"We know that members of the community don't want their lives blighted by drugs and the problems they bring and I hope today's arrests demonstrate our commitment to tackling drugs in Stretford and Old Trafford.
"The action we have taken today will no doubt have a huge impact on the supply of drugs in this area and also in the south Manchester area.
Police have released pictures of four wanted men
"The police will continue to work closely with Trafford Council and other agencies to stamp out drug dealing activity and all the criminal and anti-social behaviour associated with it.
"We will not tolerate drug dealing and we hope that the public will be able to help us tackle the problem further by identifying a number of other people we want to speak to in connection with drugs offences."
Trafford Councillor Pauleen Lane said: "Using our new powers from government we will be instigating some alley closures.
"We will also continue to use our state of the art CCTV system to monitor hot spots and deter the return of any anti social activity."
