Bolton police carried out five warrants in Farnworth as part of an investigation into stolen work vans.
The investigation was aided by information provided by the public and proactive policing.
Five men between the ages of 20 and 45 were all arrested on suspicion of conspiracy to steal motor vehicles.
Officers also seized a quantity of drugs containing all classes of illicit substances and items they believed were used to steal vehicles.
Detective sergeant Matt Quayle said: “This morning’s warrants are the culmination of a thorough investigation by our Neighbourhood Crime Team.
“Most of us know someone who has been a victim of vehicle crime of some sort, and we understand how disruptive this type of crime can be, not just financially but also emotionally, and we are focussing our efforts to tackle those who blight communities.
“I’d like to thank the community for their support in reporting information to us means we can play a part in making local neighbourhoods safer and I urge the public to continue keeping this open line of communication with police about criminal activities or expressing their concerns through contacting us directly via live-chat, speaking to your local neighbourhood officer or anonymously through Crimestoppers.
“Every bit of information, no matter how small, contributes to our investigations across Greater Manchester and could support us in tackling vehicle crime at its root.”
