SANFORD — A Sanford woman turned herself in and was charged with trafficking in oxycodone Tuesday, the latest arrest in an ongoing investigation of drug trafficking in York County.

Brittany L’Heureux, 21, turned herself in to Sanford police Tuesday after an arrest warrant was issued following a search of her home on Cottage Street. The Maine Drug Enforcement Agency alleges that its agents bought oxycodone from L’Heureux on several occasions. She was being held at the York County Jail.

The MDEA said it has arrested four other people in Sanford over the last month on charges of trafficking in oxycodone, cocaine or crack and expects more arrests in the area in the next few weeks.
