Troopers from the Wakefield State Police Post received information of possible drug activity at an Ironwood city residence.
After conducting surveillance, troopers made a traffic stop of a vehicle for equipment violations. The traffic stop resulted in a seizure of prescription medications, and two Marenisco men were arrested.
Those two men led troopers to secure a search warrant of the residence.
Police seized additional narcotics, and with evidence of drug activity, two Ironwood men were also arrested.
Michigan State Police troopers are continuing to investigate and say there could be warrants for other suspects.
