An anonymous tip helped alert police of a methamphetamine lab, leading to the arrest of three Cortland County residents Saturday.
When Cortland County Sheriffs Deputies arrived, they discovered smoke and a chemical smell coming from the garage, where the meth lab was active.
Police arrested 45-year old Robert Alberts and 28-year-old Kristina Yerian, both of McGraw, and 42-year-old Terry Maricle of Cortland.
The three were charged with unlawful manufacturing of methamphetamine and criminal possession of a controlled substance.
