16 men and one woman have been arrested in raids as part of an operation to crackdown on drug dealing in Oldham.
They were arrested when Manchester Police raided 14 addresses just after 6am on Wednesday 30th April 2014.
Officers from Oldham's Operation Caminada Organised Crime Unit launched the operation, codenamed Operation Alamos, as their response to community concerns that street drug dealing was a problem in the area.
This operation forms part of Operation Challenger, which is the Force's strategy for tackling organised crime groups across Greater Manchester.
These arrests came after months of investigations by officers from the Oldham Organised Crime Unit into the distribution of heroin.
In the raids this morning, 16 men and one woman were arrested on suspicion of drugs offences, after officers executed warrants across Oldham and Burnley.
More than 80 officers were involved in the raids and included officers from the Oldham Division and force tactical aid unit supported by Lancashire Police.
Extra officers from Oldham's Neighbourhood Policing Teams will be patrolling the area from today and the next few days to provide a visible presence and reassurance to the community.
A multi-agency plan is now in place for the area to ensure support for drug users and to prevent any further offending in the area.
Superintendant Denise Worth of the Oldham Division, said: "Today shows that the desire to rid our communities of the blight of drugs is continuous and that we shall keep tackling the issue as many times as is necessary until the problem is dealt with.
"This operation has taken months of intricate planning and dedication by officers from Operation Caminada.
"The people of Oldham have told us that they want drugs and drug dealing tackled across the borough and I hope that today's action highlights how seriously we take these crimes.
"It also sends a message out that we will not let people profit from spreading their misery in our neighbourhoods and we will continue to use all the powers and resources available to put people before the courts."
