A 27-year-old man was arrested on suspicion of production of cannabis and abstracting electricity. He remains in police custody for questioning.
The arrest followed a search of a property warranton Coalshaw Green Road, Chadderton.
Initial searches of the building uncovered 4 rooms of cannabis plants.
Police Sergeant Coggin of GMPs Oldham Neighbourhood Crime Team, said: “Our officers are working hard to crack down on drug related crime in the area.
“Oldham’s Neighbourhood crime Team focus on the execution of warrants and tasks reacting to intelligence led crime trends and district threats.
“This was a very well equipped, large cannabis farm likely involving a number of people at different levels of the drug supply chain.
“We hope that this find significantly disrupts the supply of cannabis in the area, which ultimately makes our local communities safer”.
“In order to keep on disrupting drug manufacturing in Oldham we need the public to report any information they may have to us and I would urge anyone who has information about a cannabis farm, or anyone connected to it, to please contact us so we can bring these people to justice.”
