A Lewiston woman was arrested on aggravated drug trafficking charges after being stopped by police on her way back into the state.

The Maine Drug Enforcement Agency and Lewiston Police arrested 38-year-old Elizabeth Yvonne Young on Tuesday night after stopping her vehicle on the Maine Turnpike in Lewiston. She had been the subject of an investigation into the importation of prescription pills from an out-of-state source for the past year. The pills, primarily oxycodone, were being sold in the Lewiston-Auburn area. Police say she was returning from out of state when she was stopped. A search of her vehicle resulted in the seizure of approximately 500 oxycodone pills, with a street value of $20,000.

Young is charged with 2 counts of Aggravated Trafficking in Oxycodone, 2 counts of Aggravated Importation of Oxycodone, and Possession of a Firearm by a Prohibited Person. She was arrested without incident and taken to the Androscoggin County Jail.

Police also searched Young's residence at 6 Perley Street in Lewiston and seized a handgun found at the apartment. She is prohibited from owning or possessing a firearm based on a prior federal drug trafficking conviction in 2009. Bail was set at $75,000.
