The OPP’s Drug Enforcement Unit, along with Renfrew OPP, laid several drug and firearm related charges after executing a search warrant on Wednesday. Police found marijuana growing in the residence along with a shotgun. A 30-year-old Renfrew man is now facing charges of the production and possession of a controlled substance, along with unauthorized possession and careless storage of a firearm. He’ll appear in Renfrew court in September.
